The size of the engine is a critical factor in determining how much power it can generate. A bigger engine has more room for pistons to move, which means more fuel and air can be pumped into it. This also plays a part in turbochargers, which are becoming popular in newer cars. Engine sizes are measured in cubic centimeters (cc). One liter of engine capacity is equal to 1,000cc.

Fuel economy

Fuel economy is a measure of the amount of fuel that a vehicle can use. The most common unit is liters per 100 kilometers (like). The lower the number, the better the fuel economy. Another measure is kilometers per liter (km). The more kilometers a vehicle can cover, the less fuel it needs.

Fuel efficiency is the percentage of fuel used compared to the amount of work done by the vehicle’s power source. Fuel efficiency is affected by the engine’s size, the vehicle’s mass, and speed. It’s important to note that the fuel economy number published by the manufacturers can vary widely by jurisdiction.

In Japan, the fuel economy standards are lower than in other parts of the world. This is because the average Japanese driver doesn’t drive as fast as other drivers in different regions. In the Kingdom of Saudi Arabia, the Saudi Standards Organization announced new light-duty vehicle fuel economy standards in November 2014. The new standards took effect on January 1, 2016, and will be fully phased in by January 1, 2018. The Saudi Standards Organization will review these standards in December 2018 and set new targets for 2021-2025.

The EPA also uses a metric measurement of fuel efficiency called gallons per hundred miles per kilometer. This measurement is more accurate and comparable to the standard measured fuel economy of liters per 100 kilometers. However, there are other circumstances in which a vehicle’s fuel economy can vary significantly.


FPT Industrial has introduced the V20 engine. This engine can produce 500 kW, extending its range to the top end of the market. Its compact design delivers the performance of an 18-liter within a 13-liter engine. It is the only 16-liter engine explicitly designed for heavy-duty off-road missions. The machine features second-generation Common Rail technology, which can handle up to 2,200 bar pressures.


The fuel-efficiency rules and regulations have forced truck engine makers to increase their engines’ capacity and power density. This means that there are more horsepower and lower emissions per unit of fuel. To meet these requirements, most original equipment manufacturers have made improvements to their products. However, Daimler Trucks North America has stuck with its trusted Detroit DD16 engine.
