What does 'strt' mean on a car?

strt on a car refers to the second-gear start function switch. When this switch is turned on, the automatic transmission does not start from first gear but from second gear. Its main function is to be used on slippery roads to prevent the high torque of first-gear starts from causing wheel slippage, similar to the TRC (Traction Control) function. Below is an introduction to the gears of an automatic transmission car: 1. L gear: Low gear, which limits speed. When engaged while going uphill, it maintains a high RPM and low gear state. 2. S gear: Sport mode, where the transmission can shift freely, but the shift timing is delayed, keeping the engine at high RPM for a longer time, allowing the car to move at low gear and high RPM for an extended period. 3. D gear: Drive gear, used for forward movement of the car. 4. N gear: Neutral gear, used during brief stops. 5. P gear: Park gear, used when parking; placing the gear in P stops the car's braking, preventing it from rolling. 6. R gear: Reverse gear, used when reversing. However, R gear can only be engaged when the vehicle is completely stopped; engaging R while the car is slowly moving forward can cause serious damage to the car's transmission.

What is the valve clearance of the Yuchai 6M four-valve engine?

The valve clearance of the Yuchai 6M four-valve engine is 0.25-0.30 for the intake valves and 0.30-0.35 for the exhaust valves. If there is no clearance or the clearance is too small between the valves and their transmission components in the cold state, the thermal expansion of the valves and their transmission components in the hot state will inevitably cause the valves to close improperly, resulting in air leakage during the compression and power strokes of the engine, thereby reducing power output. In severe cases, it may even be difficult to start the engine. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the maintenance of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.

Where is the Transmission Oil Filter Located?

The transmission oil filter is located inside the transmission. Below is additional information: 1. Function of transmission oil: Transmission oil is a lubricant that keeps the gear shifting system clean, ensuring proper transmission operation and extending the lifespan of the transmission components. 2. Automatic transmissions on the market: Most transmission oils can be used with automatic transmissions available on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models may vary in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated transmission oil. Different transmission oils are one of the factors affecting shift quality. 3. The fundamental difference: lies in the friction system. HFM-ATF has finer oil molecules and superior shear resistance. Under semi-clutch conditions or at the moment of engagement, the oil film on the friction material surface creates an effective suspension state, preventing slippage and cushioning powerful instantaneous impacts, resulting in smoother engagement and shifting. Additionally, the fine oil molecules significantly reduce valve sticking, ensuring smoother valve body operation.

What kind of oil does the RAV4 use?

Toyota RAV4 originally uses SN/GF-50W-20, fully synthetic oil, which should be replaced every 10,000 kilometers. The following are the functions of automotive oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of parts, it is necessary to establish an oil film of sufficient thickness between the two sliding surfaces to separate the relatively sliding parts and reduce wear, thereby extending mechanical life. 2. Cooling: The oil helps the radiator cool the engine and expels heat from the engine. 3. Sealing and leakage prevention: The oil can form a sealing ring between the piston ring and piston, reducing gas leakage and the entry of pollutants. 4. Shock absorption: When the pressure at the engine cylinder port rises sharply, it suddenly increases the load on the piston, piston chips, connecting rod, and crankshaft bearings. The load is transmitted and lubricated through the bearings, allowing the impact load to be buffered.
