What to Do When a Plug-in Hybrid Vehicle Runs Out of Battery?

What Causes the Engine Warning Light to Illuminate in the Equinox?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors referred to here include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which may trigger the engine warning light. Fuel/oil quality issues: Failure to use fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor fuel mixture combustion: Incomplete combustion can cause engine carbon buildup or knocking. When detected by oxygen sensors and reported to the ECU, the warning light will illuminate as an alert. Spark plug failure, ignition coil issues, fuel pump malfunction, or fuel line blockages can all contribute to poor combustion. Turbocharging problems: Issues with the intake boost piping or turbocharger may also trigger the engine warning light. The most common is turbocharger damage, often accompanied by oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Intake problems: Air intake issues may cause engine pipe blockages, potentially triggering the warning light. A dirty air filter that hasn't been cleaned regularly can lead to intake problems. Exhaust system issues: Exhaust faults may also activate the engine light. Common causes include rear oxygen sensor failure, catalytic converter problems, or exhaust camshaft and bearing issues. Using leaded gasoline, certain lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can all contribute to catalytic converter failure. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or the anti-theft controller doesn't match the engine ECU, the system may prevent normal engine operation while illuminating the warning light. When the engine warning light illuminates, follow these steps: First, check if the engine is operating normally. If there's noticeable shaking, smoke emission, or other abnormalities, avoid restarting the engine. Particularly important - never restart if the red warning light is on. If the engine can start, turn off the ignition for 5-10 minutes. Then, without pressing the brake pedal, press the start button once or turn the key halfway to the ON position (without depressing the clutch). The vehicle will initiate a self-check function after powering on. Observe whether the warning light turns off after 5-10 seconds. If the light remains on, visit a service center promptly. Technicians can use diagnostic tools to read trouble codes, identify specific issues, and perform targeted repairs.

What brand of engine is used in the Changan Eado DT?

The engine of the Changan Eado DT is independently developed by Changan Automobile and produced in Chongqing, so it belongs to a domestic engine. The engine model of the Changan Eado DT is JL478QEE, with a maximum power of 92kW, a maximum torque of 160Nm, and a maximum horsepower of 125. For the daily maintenance of the Changan Eado DT's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid failures, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the 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 blocked and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to pass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and the cylinder wall, mixing with metal powder generated by part wear to form sludge. A small amount of sludge remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and the engine.

Where are Mitsubishi engines produced in China?

Mitsubishi engines are produced in Shenyang, China, by Shenyang Aerospace Mitsubishi Engine Manufacturing Co., Ltd., and are considered domestically manufactured engines. Models equipped with Mitsubishi engines include: BYD, Great Wall Haval, Landwind, Venucia Star, Leopaard, etc. Among them, the Venucia Star uses the A415TD engine model, which delivers a maximum horsepower of 190 hp, a maximum power output of 140 KW at 5500 rpm, and a torque of 260 Nm between 1500 to 4500 rpm. For daily maintenance of Mitsubishi engines, 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 equipment 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 grade of lubricating oil will degrade during use. After a certain mileage, performance deteriorates, leading to various engine issues. 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 becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. 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 flush the radiator. Removing rust and scale deposits not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

How to Handle a Traffic Accident?

Calling the police immediately helps to secure the accident scene and clarify the responsibilities of both parties. Moreover, it cannot be ruled out that the perpetrator may have been drinking. The traffic accident identification report is the most powerful evidence to distinguish the responsibilities of both parties. Courts generally recognize the liability ratio stated in the traffic accident identification report.
