Oil Change And Inspection. It essentially consists of two power systems, considering the basic design of a hybrid vehicle, the first of which is called the internal combustion engine and its associated system. Therefore, if you want a hybrid car to have high fuel efficiency, you should pay careful attention to its engine performance as well. According to the manufacturer, one of the most important periodic engine maintenance procedures is the timely replacement of engine oil. Maintaining high-level engine oil not only reduces friction between metal parts but also reduces internal cleaning, temperature control, reduced operating noise, increased fuel efficiency, emission control and increased longevity.

The engine oil should therefore be changed within the specified timeframe and, if not, the above requirements will not be properly met.

This is not just an oil change service. In this valuable service, there are a number of other systems that need to be checked over the distance the vehicle has been driven. This is the name of the Oil Change And Inspection.

When a car is serviced, key components such as engine oil, gear oil, Brake Fluid, Clutch Fluid, Differential Oil will be changed either within mileage or months from the date of conversion, for example, Engine oil will be changed either within 5000km or 6 months from the date of conversion.

This means that the maximum quality time of the oil after application to the engine is 6 months and that if you run 5000km before that time, it should be changed before 6 months. Coolant should be changed based on driving distance and time.

This is due to the fact that the oil in the engine is present in the engine oil sump, but is subject to atmospheric pressure, environmental factors and constant thermal stress during engine operation. Adverse effects include changes in oil and tar deposits, increased friction between the metal parts of the engine due to change in density, increased payload, poor temperature control, increased noise.

Thus, each system has its own set of maintenance periods, which is due to the long-term performance of the vehicle, as well as its emission control and fuel efficiency. It is therefore important to keep in mind that timely service on product instructions will ensure the longevity of your vehicle and minimize potential costly repairs.

When we provide services to you, we refer you to qualified and experienced technicians well trained at NMAHTA, theoretically and practically who always strive to provide an efficient, friendly and reliable service. Several key vehicle systems are tested at each service.

Transmission Fluid Change. The mechanical power generated by the engine and electric motors, the basic power converters of the hybrid car, is controlled and transmitted through the gearbox, commonly known as the gearbox, to the wheels. Many hybrid cars also have electric motors, and these cars' electronic components work electronically on modern cars to reduce transmission delays. The resulting mechanical power is transferred to the wheels without unnecessary expense, which increases the vehicle's fuel efficiency and travel comfort.

Maintenance of the hybrid system of a Hybrid Vehicle is therefore a very important requirement, and gear oil is very important for the proper maintenance of the internal hydraulic pressure, for the reduction of the friction of mechanical parts such as gear wheels, for power splitting, for the cooling of electric motors and for the protection of their insulation resistance. Performs it. Oil expiration due to changes in the driving distance and environmental conditions of the vehicle and changes in the heat can cause defects in the internal parts due to this change in the valuable properties of the vehicle. A special piece of work.

This is a very important requirement for the longevity of the vehicle, to minimize costly future repairs and to increase fuel efficiency and control of emissions. This service provided by us is always based on the recommendations of the manufacturing company and is provided technically and efficiently by experienced technicians using high quality raw materials.

Inverter and Radiator Cooling System Maintenance. The main components of the first and second chapters of the hybrid vehicle, such as the hybrid battery, the power inverter, the hybrid transmission and the internal combustion engine, must all be maintained at the specified temperature range for maximum efficiency. The cooling systems thus designed may be of two types.

Classified as follows;

1. The active cooling system
2. The passive cooling system

Depending on the design of the car, one of the two methods used by the manufacturer is to create cooling circuits for each of them, either individually or individually.

The power inverter unit, often referred to as the brain of the engine and hybrid system, is an active cooling system that is often designed using a hydraulic cooler to meet the cooling needs of these systems.

The coolant used here is chemically designed to operate on the same system, the inverter coolant is called the inverter coolant, and the engine cooler is called the radiator coolant.

These are special anti-rust, anti-nitrate, anti-phosphate, anti-borate, etc. chemicals with special properties. They therefore vary from system to system depending on the nature of the cooling system, the design, the cooling range and the absorption of heat. Also, their original properties change due to chemical changes that occur during operation, which have a serious effect on the cooling units. As with the engine oil in the car, the coolant has to be changed again depending on the environment, time and driving distance of the vehicle.

This is stated by the manufacturer in the vehicle specific service manual and it is recommended that the coolant be changed first on the basis of the driving distance and the time of arrival. Many complex electronic circuits, such as the power inverter, are integrated into one unit, causing the hybrid system to overheat rapidly as operating speed and load limits increase, in which case.

these circuits overheat and require active temperature control to maintain the same function or not. Destructed and re-applied at a high cost. The coolant passes through the cooling tubes created between them.

The coolant used depends on the chemical compounds used in their design and classified into three categories.

IAT: Inorganic Acid Technology

IAT is the traditional green stuff that is pretty much only used on older cars that predate the late nineties. The lifespan of traditional coolant is about two years.

OAT: = Organic Acid Technology

OAT is used today because it offers silicate-free protection of all metals, and for a longer period of time: it’s the long life (LLC) or extended life (ELC) coolant and has a service life of five years or 150,000 miles. Colours are mostly red and orange, but also green, pink and blue.

HOAT: = Hybrid Organic Acid Technology

This is also used today, and is usually orange or yellow. A mix of IAT and OAT, the orange cocktail – and only the orange -- contains 10 percent recycled coolant.

In order to distinguish these from each other, the above is given a unique colour. Therefore, it is important to pay attention to the original colour of the cooler when replacing it. Therefore, the technician should pay attention when replacing the cooler in service and their type and always make sure to use only the approved cooler. And not using the correct types.

Our company uses state-of-the-art equipment to check the quality of the coolant in each service and to recommend and use only the essential coolant quality approved by the manufacturer. Not only in hybrid cars, but also in modern car engines, temperature control is controlled by computer programs using an electronic speed control water pump. This minimizes the engine power loss caused by the water pump with the drive belt and the temperature control difficulties associated with the up and down speed of the engine and allows the temperature to be adjusted quickly and successfully.

Depending on the design of the cooling system of the typical car and the type of coolant used and the environmental conditions under which the vehicle is driven, the cooler replacement time varies and is generally considered to be in line with the driving conditions in our country. It should be serviced on a first-come, first-served basis after every 30,000 km or six months of quality testing.

ECB System Brake Fluid and Maintenance. Brake, which belongs ‘active safety’ category, is the most important system when running a vehicle. Among the basic driving conditions of a hybrid vehicle, the regenerative brake function mainly recharges the hybrid battery by directing the vehicle to generate electricity without consuming the mechanical power used during deceleration and braking. Essentially, it recharges the hybrid battery by directing it to generate electricity. This can increase the range of Assist and EV racing on re-run and keep the overall fuel efficiency and organic emission control at a high level, as the power required by the engine can be maintained at maximum efficiency limits.

Each hybrid car is equipped with a computer brake control system that is different from the average car, as it is electronically controlled for this function. This is called the Electronic Brake Control System (ECB).

The system also includes a hydraulic brake system that is more complex than in a regular car, and maintaining its hydraulic pressure within the specified range is essential for the system to function. As a result, the longevity of the brake system operating units, the quality of the brake fluid is a crucial factor in maintaining proper functioning for a long period of time and, if the basic features are to remain the same for a long period of time, the running condition of the vehicle should be taken into account and properly serviced.

Failure to do so will result in an improper operation of the regulator and a failure of fuel efficiency, which in turn will have a serious impact on safety. It is therefore always necessary to use the brake fluid that matches the number recommended by the manufacturer. Due to the prolonged existence of Brake Fluid due to untimely evaporation, the addition of water vapor causes the boiling point of the Brake Fluid to drop and the resistance to decrease is due to the slug caused by the contaminated fluid trapped between the tiny holes in the moving units and valuable units such as the Brake Modulator. Causes shrinkage, drop in pressure, and leakage. The quality of brake fluid should therefore be inspected in al services to minimize expensive repairs.

Brake Fluid Replacement varies with the driving distance of a vehicle and driving environment also should be changed every 50000km or every 2.5 years before arrival, by taking into account of driving conditions in our country. It is also advisable to check the quality of it at the service of every 5000 km or every 10000 km.

Once the Brake Fluid has been changed, it must be bled using OEM scanning equipment and recalibrated to the position of the most sensitive operating units. We check the quality of the brake fluid and the system pressure in every km5000 or 10000km for every hybrid vehicle that comes into service and recommends on the services required. Also use only the manufacturers approved brake fluid and updates computer data through the OEM scanning tool, preparing the vehicle for stress-free journeys that ensures safety.

Duel Clutch Fluid Change. The Duel Clutch Transmission (DCT) is one of the most popular transmission systems used in modern hybrid vehicles. This can be seen in car models such as Honda Vezel and Fit. The manual transmission used in older cars is a further upgrade and is also known as the AT MT, as the transmission is designed to move electronically from one gear to another in less than 200ms. It is essentially a 7-speed manual transmission with 13, 5,7 gears in one axle and 2,4,6 gears in another axle with a separate dry clutch for each of the two axles. The clutch therefore acts separately when moving from one gear to another, which significantly reduces the latency between the gears and gives the driver the feeling of an automatic gearbox while driving.

Its clutch performance is a very important factor in moving from one gear to another and keeping the time spent there to a minimum of 200ms.

The dual clutch is assembled into a single assembly and is operated and disconnected by a device called a hydrostatic clutch actuator. Clutch Fluid is used to control the pressure exerted by these units on the clutch. During long-term use, the addition of water vapor also changes over time, weakening the pressure control and causing the transmission to fail. The clutch assembly unit is very expensive and represents more than 10% of the market price of the used car at our overseas price.

At the same time, mechanical faults in the gearbox are also developing, leading to costly repairs. It is therefore essential for the customer to pay attention to and replace the clutch fluid in the Duel clutch system in a timely manner.

Usually, the clutch fluid should be changed after every 15000 km of operation or after 6 months as recommended by the manufacturer. Use the fluid in accordance with the approved number and use the standard clutch fluid. We check the level of the clutch fluid and its quality every 5000km for vehicles coming into service. We also ensure that highquality clutch fluid is used in this service.
