The traditional theory believes that the thermal efficiency of general steam turbines is 4%-8%; the thermal efficiency of gasoline engines is 25%-35%; and the thermal efficiency of diesel engines is 35%-45 %.The reason why the engine cannot achieve 100% thermal efficiency is mainly related to the following aspects: friction loss.
Engine thermal efficiency, also known as "engine effective efficiency". It refers to the ratio of the thermal equivalent of the effective power of the engine to the heat content of the fuel consumed per unit of time. It is used to evaluate the economy of the engine as a thermal engine. The thermal efficiency of different engines and power units is different, but the value is less than 1.

The thermal efficiency of gasoline engines is between 25% and 35%.Gasoline engines will lose 25%-35% of energy when converting the thermal energy of the fuel into effective power. Compared with diesel engines, gasoline engines have lower thermal efficiency. The advantages of gasoline engines include small size, light weight, easy maintenance, large output power and fuel saving.
Hello: Engine efficiency refers to the effectiveness of the engine using the chemical energy of the propellant. When the engine is working, only part of the thermal energy contained in the fuel is converted into propulsion, and the rest is lost in the form of thermal energy or kinetic energy.

The thermal efficiency of a gasoline engine refers to the ratio between the mechanical work output by the engine and the chemical energy generated by burning fuel. That is, how many calories are converted into effective work. At present, the thermal efficiency of the engine is generally only a little more than 30%. Gasoline Engine: GasolineEngine is an engine that uses gasoline as fuel and converts internal energy into kinetic energy.
Engine thermal efficiency, also known as "engine effective efficiency". It refers to the ratio of the thermal equivalent of the effective power of the engine to the heat content of the fuel consumed per unit of time.

It is similar to the relationship between the amount of food you eat and the fat man. Engine thermal efficiency is one of the important data to measure the technical level of the engine. Of course, the improvement of thermal efficiency will also bring a direct result, that is, affecting the fuel consumption level of the car.
3. The thermal efficiency of the engine cannot reach 100%.One of the reasons is that the engine material cannot accept such a high temperature. The engine is made of metal. The metal has a certain resistance to hot spots. If it exceeds a certain temperature, it will be deformed, resulting in damage to the parts. Therefore, part of the heat energy must be transferred to the coolant, that is, heat dissipation.
4. That is to say, heat energy cannot be completely used for work, so it is bound to have certain losses in the process of energy conversion.
5. [Pacific Automobile Network] The thermal efficiency of the automobile refers to the ratio between the mechanical work output by the engine and the chemical energy generated by the combustion of fuel, that is, the evaluation of how much heat is converted into effective work. When the engine is working, only part of the heat energy contained in the fuel is converted into propulsion, and the rest is lost in the form of heat energy or kinetic energy.
6. Generally speaking, thermal efficiency refers to, when the fuel is fully burned in the engine, the heat generated is converted into mechanical energy and utilized. And this conversion ratio is what we usually call the thermal efficiency.
The factors affecting the theoretical thermal efficiency are: combustion temperature, exhaust temperature, compression ratio, and exhaust pressure.
The thermal efficiency of the engine is divided into two types: indication thermal efficiency and effective thermal efficiency, which mainly depends on the source of "output power". First of all, let's talk about the thermal efficiency of the indicator. The "indication" here represents the "actual cycle indication work", that is, the work consumed by pushing the piston.
The thermal efficiency of the thermal engine is related to whether the fuel is fully burned, mechanical friction is overcome, and exhaust gas is generated.To improve the efficiency of the thermal engine, it is necessary to let the fuel burn fully and reduce the loss of heat, that is, to reduce the loss of mechanical friction, reduce mechanical heat dissipation and exhaust gas to take away heat.

If it is represented by ηt, then there is ηt=W/ Q1=(Q1-Q2) / Q1=1- Q2/Q1.
6. --Knowledge point: The best thermal efficiency can only be achieved in an ideal operating environment. The temperature of the body and coolant when the car is cold started is very low. At this time, the heat energy generated by combustion will be absorbed in reverse. At this stage, the thermal efficiency will be reduced due to "overcooling", and the proportion will be quite high.
