    If the thermal efficiency of the car engine can reach 100%, what will be the consequences?

    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.

    If the working form of the internal combustion engine reaches 100%, it is impossible to achieve it in the foreseeable future. The way the internal combustion engine pushes the piston through combustion will inevitably produce a large amount of heat loss.

    So if the working principle of the engine is changed, can it achieve 100% thermal efficiency? According to the second law of thermodynamics, Kelvin, it is impossible to create a thermal machine that can convert all of them into work by absorbing heat from a single heat source, that is, whether the heat can work completely or not, there must be some losses.

    such asIf the heat efficiency reaches 100%, it means that no heat is generated during combustion. At the same time, no consumption is generated when passing through all parts, and it is also required to be fully burned during combustion. Therefore, theoretically speaking, it is impossible to achieve 100% of the thermal efficiency of the engine with the current technical level.

    Last year, the public issued a new 5T engine in the EA211 series at the Vienna Motor Show. The compression ratio of the new engine can reach 1533601, with a variable geometric segment turbine, a 350-bar fuel nozzle, and a thermal efficiency of up to 35%.

    The thermal efficiency is the ratio of the mechanical work output by the engine to the chemical energy generated by burning fuel. Simply put, which part of the energy generated by the fuel becomes the engine, so why is the output power less than 100%?What will happen when the output power reaches 100%? The engine material can't accept such a high temperature.

    What is the work efficiency formula of the engine?

    Efficiency formula: η=W useful/Q heat dissipation, η=(P*t)/(m*g). The ratio of the thermal equivalent of the effective power of the engine to the heat content of the fuel consumed per unit time is called thermal efficiency (effective efficiency), which is used to evaluate the economy of the engine as a thermal engine.

    Calculation formula for engine efficiency: engine efficiency = mechanical power/total energy input.

    The power indicated on the sign of the engine is the maximum output power of the engine under normal working conditions. The two most of the performance indicators of automobile enginesThe basic parameters are the number of cylinders and the working volume of the cylinder, which is the usual exhaust volume.

    Generally about 12V to 15V. Generally, automobile alternators only define the rated working voltage and rated output current, and usually the power of the automobile generator is not marked on the nameplate. The following formula is for reference only.

    What is the mechanical efficiency of automobile engines

    The mechanical efficiency of gasoline engines is about 35%, that is to say, as long as 35% of the energy is converted into the useful work we need, the remaining 65% of the energy is wasted. The main waste is heat, as well as mechanical friction to attack, sound, etc.

    Ordinary four-stroke gasoline engines only have 20%~40%, firewoodThe oil engine is higher, and the mechanical efficiency of the rotor engine is higher, exceeding 60%. If you install a turbojet engine, the efficiency is very high.

    The mechanical efficiency of the engine is about 80%-90%, and the mechanical efficiency of the supercharged engine is higher. The thermal efficiency of gasoline engines is about 23%-40%; the thermal efficiency of diesel engines is about 40%-50% (the thermal efficiency of low-speed diesel engines can exceed 50%).

    Engine efficiency formula

    1. The method of calculating engine efficiency (power): power (w) = torque (Nm) × speed (rpm) × 2π /60, after simplifying the calculation, it becomes: power (kw) = torque (Nm) × rotation speed (rpm)/9549.

    2. The engine efficiency formula is - η=W useful/Q heat dissipation, η=(P*t)/(m*g). The formula is explained as - the ratio of the thermal equivalent of the effective power of the engine to the heat content of the fuel consumed per unit time is called thermal efficiency (effective efficiency), which is used to evaluate the economy of the engine as a thermal engine.

    3. SendThe formula for motivation efficiency is - η=W useful/Q heat dissipation, η=(P*t)/(m*g). The explanation of this formula is that the ratio of the thermal equivalent of the effective power of the engine to the heat consumed by fuel per unit time is called thermal efficiency (effective efficiency) to evaluate the economy of the engine as a thermal engine.

    4. Efficiency formula: η=W useful/Q heat dissipation, η=(P*t)/(m*g). The ratio of the thermal equivalent of the effective power of the engine to the heat content of the fuel consumed per unit time is called thermal efficiency (effective efficiency), which is used to evaluate the economy of the engine as a thermal engine.

    5. According to the Baidu library query, the formula for engine efficiency is η=W useful/Q heat dissipation, which can also be expressed as η=(Pt)/(mg).

    6. Engine efficiencyType: Engine efficiency (η) = output power (P_out) / input heat energy (Q_in). This formula represents the ratio between the power generated by the engine from the input heat energy and the total input heat energy.

    The main factors affecting the efficiency of the car engine are

    1. The fuel consumption of the engine has a decisive impact on the fuel consumption of the car, and the fuel consumption of the engine is determined by the structure and performance of the engine. There are five main aspects of the impact of the engine on the fuel consumption of the car: the transmission system. The higher the efficiency of the automobile transmission system, the smaller the energy loss in the process of transmitting power, the lower the fuel consumption of the car.

    2. The intake pipe is very important for the normal operation of the engine., if the intake pipe is too dirty, it will lead to a decrease in efficiency, so that the engine cannot operate within the normal output power range, which aggravates the wear and aging of the engine.

    3. The number of valves: indicates the number of valves contained in each cylinder. There are intake valves and output valves. The number of valves can generally affect the emission and rotation speed of an engine.

    4. Here, we have sorted out some factors that affect the performance of cars for your reference. First, the power of a car (1) Maximum speed refers to the maximum driving speed that can be achieved on a good horizontal road surface (such as dry, flat and clean asphalt or cement road surface) when the car is fully loaded.

    5. There are many factors that affect the inflation efficiency of automobile engines. The following are some common reasons: filterClearance problem: The air filter in the engine intake system may be affected by dust, particles, insects and other impurities, thus blocking the air flow and reducing the efficiency of engine inflation.
