What is the difference between a red light and a yellow light on the engine?

An illuminated red light on the engine indicates an emergency state. You should not continue driving and must pull over safely as soon as possible, then contact a repair facility to assess the engine's condition. There are two common scenarios when the engine red light comes on: The first is insufficient oil pressure, signaled by the oil pressure warning light. When this light activates, it means oil pressure is inadequate. The second is the coolant warning light, which illuminates when the coolant level drops below the minimum threshold or due to overheating. Reasons for the engine malfunction light to activate include: Poor fuel quality leading to incomplete combustion in the cylinders and carbon buildup; excessive engine mileage causing weakened spark plug performance; mechanical aging of vehicle components; and issues with water temperature, crankshaft position, air flow, intake temperature, oxygen sensor damage, poor contact, or signal interruption.

What does the number of cylinders in an engine mean?

The cylinder in an engine refers to the combustion chamber. A cylinder is a cylindrical cavity within the engine where a piston moves under the pressure or expansion force of the working fluid. The cylinder and cylinder head must be assembled together to form the combustion chamber. An engine typically has multiple cylinders. The sum of the working volumes of all cylinders is called the engine displacement, measured in liters (L). Here is some relevant information about car engines: Introduction: A car engine is the device that provides power to the vehicle, acting as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.

What are the possible causes of engine acceleration weakness?

Possible causes of engine acceleration weakness are as follows: Engine intake pipe leakage: The intake system contains many intake manifolds or various valves. Any leakage in these components can allow unwanted gases to enter, resulting in either excessively high or low concentrations of the air-fuel mixture in the intake manifold. This ultimately leads to symptoms such as intermittent engine shaking or weakness during idling. Fuel system blockage or malfunction: Due to a blocked fuel tank vent, clogged fuel tank switch, fuel filter, or fuel lines between the tank and carburetor, the engine may not receive the required amount of fuel during idling. This causes the air-fuel mixture to become lean, resulting in weakened engine power output and idle shaking.

What Causes Abnormal Noise During Engine Acceleration?

Acceleration is the operation that most tests the quality of a car, and many car problems will manifest during acceleration, so regular maintenance is essential. The reasons for abnormal noise during engine acceleration are: transmission noise; valve noise; engine noise. The reasons for abnormal noise after a cold start are: belt slipping on the generator: intense friction and vibration between the belt and the pulley produce noise at a certain frequency. Belt slipping may be due to a loose belt, so it's important to have it checked at a repair shop promptly; usually, it's the sound of the valves: after a car has been parked for a long time, the engine oil returns to the bottom, meaning the top of the engine, or the valve chamber, will have less oil. Because the valves lack the sealing and lubrication provided by the oil, you may hear a lot of noise the next morning when starting the car.

What is the horsepower of the Mazda Axela engine?

The Mazda Axela engine is produced by Nanjing Changan Ford Mazda Engine Co., Ltd., and is a domestically manufactured engine. The 1.5L version of the Mazda Axela engine is model SKYACTIV-G, with a maximum horsepower of 117, maximum power of 86kW, and maximum torque of 148Nm. The 2.0L version is model SKYACTIV-X, with a maximum horsepower of 158, maximum power of 116kW, and maximum torque of 202Nm. For daily maintenance of the Mazda Axela 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 in 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 filter. The quality of any grade of 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, it may rupture the filter or open the safety valve, bypassing through the relief valve and carrying contaminants back to the lubrication areas, accelerating engine wear and increasing 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 a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What Are the Causes of Intermittent Engine Misfire in a Cylinder?

Engine intermittent misfire in a cylinder can be caused by the following reasons: 1. Clogged or aged fuel injector: As the vehicle ages, carbon deposits accumulate over time, leading to clogged fuel injectors. Fuel injectors that have been subjected to long-term high-pressure gasoline flow may experience severe aging. These conditions can cause delayed solenoid valve switching, excessive fuel injection, and overly rich air-fuel mixture in the engine, resulting in intermittent misfire in a cylinder. 2. Spark plug issues: Spark plugs are one of the most easily damaged components in a car. Any malfunction in the spark plugs can lead to intermittent misfire in a cylinder. 3. Damaged ignition coil and cylinder wire: If these components malfunction, the spark plug cannot ignite properly, leading to misfire in a cylinder.
