Car randament (engine efficiency)

In summary, car randament, also known as engine efficiency, is a measure of how well an engine converts fuel into work or energy. It is calculated by dividing the amount of work or energy produced by the engine by the amount of fuel consumed. There are several factors that can affect car randament, including engine design, fuel type and quality, driving habits, and maintenance. The best way to improve car randament is to ensure that the engine is properly maintained and that the vehicle is driven efficiently. Car randament is not the same as fuel economy, as fuel economy measures how far a vehicle can travel on a certain amount of fuel while car randament measures the efficiency of the engine.

Diesel and otto car cannot have randament of 100 per cent, practically. But teoretically they could have?

Welcome to PF.

Compression of air results in loss of heat energy to engine block and cooling system.
So Diesel or Otto cycle engine will never be 100% efficient.

Note; In Romanian, randament = efficiency.

1) What is car randament?

Car randament, also known as engine efficiency, is a measure of how well an engine converts fuel into work or energy. It is typically expressed as a percentage, with higher percentages indicating a more efficient engine.

2) How is car randament calculated?

Car randament is calculated by dividing the amount of work or energy produced by the engine by the amount of fuel consumed. This calculation takes into account factors such as engine size, fuel type, and driving conditions.

3) What factors affect car randament?

There are several factors that can affect car randament, including engine design, fuel type and quality, driving habits, and maintenance. For example, a well-maintained engine will typically have a higher randament compared to one that is not regularly serviced.

4) How can car randament be improved?

The best way to improve car randament is to ensure that the engine is properly maintained and that the vehicle is driven efficiently. This includes performing regular tune-ups, using high-quality fuel, and avoiding aggressive driving habits such as rapid acceleration and braking.

5) Is car randament the same as fuel economy?

No, car randament and fuel economy are not the same. While car randament measures the efficiency of the engine, fuel economy measures how far a vehicle can travel on a certain amount of fuel. A car with a high randament may not necessarily have a high fuel economy if it is driven inefficiently.
