Where is the 4A15J1 engine produced?

4A15J1 engine is domestically produced, a self-developed engine by GAC Trumpchi. This engine is used in GAC Trumpchi models, such as the Trumpchi GM6, which is equipped with the 4A15J1 engine. It has a maximum power of 126kW, a maximum torque of 265 Nm, and a maximum horsepower of 171. For daily maintenance of the 4A15J1 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and oil filter. The quality of any lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

How to continue using ETC after removal?

To continue using ETC after removal, the vehicle owner needs to bring relevant documents and equipment to the ETC service point and have the staff reactivate it. ETC, also known as Automatic Road Toll Collection System or Electronic Toll Collection System, is a dedicated road toll method for toll roads, commonly seen on highways, toll bridges or tunnels, and certain sections of city centers to alleviate urban traffic congestion. The fully automatic electronic toll collection system is one of the service functions of the Intelligent Transportation System, particularly suitable for use on highways or busy bridge and tunnel environments.

Does the dash cam keep recording when parked?

When parked, the dash cam does not continue recording. A dash cam is a device that records images and sound-related information during vehicle operation. Its functions include: 1. Recording the entire driving process with video and audio; 2. Continuously filming while driving, simultaneously logging time, speed, and location in the recording; 3. Serving as a DV for capturing life moments or functioning as a home surveillance system. In the event of an accident, playback of the recorded footage allows traffic police to handle incidents swiftly and accurately, enabling quick clearance of the scene to restore traffic flow while preserving valid evidence of the occurrence, thereby contributing to a safe and smooth traffic environment.

Is it necessary to install a protective plate under the engine?

It is necessary to install a protective plate under the engine. Reasons for installation: Installing it is to protect the vehicle's engine, specifically by placing a plate-shaped protective device under the chassis. This prevents the exposed parts of the engine from being directly damaged. It also helps isolate dirt from the ground, keeping the engine cleaner. Function of the engine bottom: The bottom of a car engine typically has a layer of basic protection made of felt material, which mainly serves to isolate dirt from the ground. Its effectiveness in preventing scratches and bottoming out is very limited.

What is the purpose of cleaning fuel injectors?

Cleaning fuel injectors serves the following purposes: It can improve the issue of vehicle exhaust emissions pollution. When fuel injectors malfunction due to carbon deposits, the mixing and combustion of the combustible air-fuel mixture will be affected to some extent, leading to increased pollution in vehicle exhaust emissions. A fuel injector is essentially a normally closed valve. When the electromagnetic coil is energized, it generates a magnetic force that lifts the needle valve, opening the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a fine mist that facilitates complete combustion. As one of the key components of an electronic fuel injection engine, the performance of the fuel injector significantly impacts the overall engine performance.

Why Does the Engine Noise Increase After an Oil Change?

There are several reasons why engine noise may increase after an oil change: 1. Overfilling of engine oil: When there is too much oil in the engine, it creates unnecessary resistance to the rotation of the crankshaft, affecting power output, increasing fuel consumption, and consequently raising noise levels. 2. Unsuitable oil viscosity: If the oil viscosity is too high, it creates greater rotational resistance when the engine is cold, leading to insufficient lubrication and increased noise during cold starts. 3. Severe engine carbon buildup: Over time, engine oil becomes thinner, and carbon deposits accumulate. When new oil is first added, the engine may not immediately adapt to the oil's viscosity, resulting in increased engine noise.
