What is the working principle of an engine oil pump?

The principle of the oil pump is that when the engine is running, the drive gear on the camshaft drives the transmission gear of the oil pump, causing the drive gear fixed on the drive gear shaft to rotate, thereby driving the driven gear to rotate in the opposite direction, sending the oil from the inlet chamber along the tooth gap and pump wall to the outlet chamber. In this way, a low pressure is formed at the inlet chamber, creating suction to draw oil from the oil pan into the oil chamber. The specific introduction is as follows: 1. The function of the oil pump is to raise the oil to a certain pressure and then forcibly deliver it to the moving surfaces of various engine components. The structural forms of oil pumps can be divided into two types: gear-type and rotor-type. Gear-type oil pumps are further divided into internal gear-type and external gear-type, with the latter generally referred to as gear-type oil pumps. 2. It is used to increase oil pressure and ensure a certain oil volume, serving as a component that forcibly supplies oil to various friction surfaces. Internal combustion engines widely use gear-type oil pumps and rotor-type oil pumps. Gear-type oil pumps have a simple structure, are easy to manufacture, reliable in operation, have a long service life, and provide high oil pressure, making them widely used.

Does the rotary engine consume a lot of fuel?

Rotary engines have relatively high fuel consumption. Here is some information about rotary engines: 1. Reasons: Due to the lack of high compression ratio found in reciprocating engines, rotary engines often experience incomplete combustion of fuel in the combustion chamber during operation, which can lead to increased fuel consumption in vehicles. 2. Applications: Currently, rotary engines are only used in the Mazda RX-7 and Mazda RX-8. Moreover, rotary engines have a limited lifespan as they consume not only fuel but also the life of the engine itself. 3. Characteristics: The rotary engine is a type of engine with a unique working principle and structure.

What Causes the Engine Warning Light to Illuminate in an Audi?

There are two scenarios when the engine warning light comes on: the vehicle has an engine system fault such as sensor issues, maintenance problems, fuel quality concerns, poor combustion of the air-fuel mixture, intake problems, turbocharging issues, exhaust system faults, or anti-theft system malfunctions. During vehicle startup, the engine performs a self-check, but in this case, the light should turn off after the self-check is completed. If the engine warning light remains illuminated for an extended period, it is advisable to promptly visit a service station for troubleshooting. Below is a detailed explanation of each potential fault: Sensor Issues: Sensors include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, which triggers the engine warning light. In such cases, it is essential to seek professional inspection at a service center to eliminate safety hazards promptly. Maintenance Problems: Poor engine maintenance is the most common cause of the engine warning light illuminating. Vehicles have specific maintenance schedules, and failure to adhere to these schedules, combined with poor driving habits, can increase the engine's operational burden. Eventually, the engine warning light will illuminate to alert the owner of a potential fault. Fuel Quality Issues: This refers to both fuel and engine oil. The fuel used in vehicles typically has a specified octane rating, and engine oil can be semi-synthetic or fully synthetic. Manufacturers usually recommend the appropriate fuel octane rating and oil type for the vehicle. If the owner fails to follow these recommendations over time, it can lead to engine wear, triggering the warning light. Always use the recommended fuel octane and engine oil grade for your vehicle. Poor Combustion of Air-Fuel Mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture. This leads to engine carbon buildup or knocking, which the oxygen sensors detect and report to the ECU, resulting in the warning light illuminating as a warning. Intake Problems: The engine requires air for combustion, and the air filter plays a crucial role in this process. If the air filter is dirty or not cleaned regularly, it can affect the engine's air intake. Over time, this may lead to blockages and, in severe cases, trigger the engine warning light. Turbocharging Issues: Problems with the intake boost pipes or turbocharger can also cause the engine warning light to illuminate. The most common issue is a damaged turbocharger, which may also result in oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust System Problems: Faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings can trigger the engine warning light. The most frequent issue is a malfunctioning catalytic converter, which can be caused by using leaded gasoline, lead- or silicon-based oil additives, physical damage to the catalytic converter, or fuel system faults. Anti-Theft System: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller is incompatible with the engine ECU, the anti-theft system can prevent the engine from operating correctly, and the engine warning light will illuminate.

Which gear should be used when waiting at a red light?

When the red light is about 10 seconds, use D gear. When the red light is more than 30 seconds, use N gear. Here is a partial introduction about gear selection when waiting at a red light: 1. Red light about 10 seconds: Automatic transmission models generally have four gears, namely P, R, N, and D. D gear is the drive gear. Following the principle of not frequently shifting gears, if the red light time is very short, about 10 seconds, then there is no need to switch gears. Just keep it in D gear and step on the brake. 2. Red light more than 30 seconds: If the red light time is more than 30 seconds, and some urban intersections can even have red lights lasting up to 99 seconds, it is generally recommended to shift to N gear, which is the neutral gear, and then pull the handbrake. This allows you to release your foot and take a slight rest.
