How to Read Car Engine Specs
When you’re shopping for a new car, it’s important to understand the engine specs. These specs can tell you a lot about the car’s performance, fuel efficiency, and emissions.
Here’s a guide to help you understand the most important engine specs:
Displacement
Displacement is the total volume of the cylinders in an engine. It’s measured in liters or cubic centimeters (cc). A larger displacement means that the engine can hold more air and fuel, which can lead to more power. However, larger displacement engines also tend to be less fuel-efficient.
Power
Power is the amount of work that an engine can do in a given amount of time. It’s measured in horsepower (hp) or kilowatts (kW). A higher power rating means that the engine can produce more power, which can lead to better acceleration and top speed.
Torque
Torque is the twisting force that an engine produces. It’s measured in pound-feet (lb-ft) or newton-meters (Nm). A higher torque rating means that the engine can produce more torque, which can lead to better towing and hauling capabilities.
Compression ratio
The compression ratio is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to the volume of the cylinder when the piston is at the top of its stroke. A higher compression ratio means that the air and fuel in the cylinder are compressed more, which can lead to more power and fuel efficiency. However, higher compression ratios can also lead to engine knock.
Valve timing
Valve timing refers to the timing of the opening and closing of the intake and exhaust valves in an engine. The timing of the valves can affect the engine’s power, fuel efficiency, and emissions.
Fuel system
The fuel system is responsible for delivering fuel to the engine. The type of fuel system can affect the engine’s performance, fuel efficiency, and emissions.
Emissions
Emissions are the gases that are released from an engine. The type and amount of emissions can affect the environment and your health.
