It's impossible to give a definitive answer to how much fuel a 1000cc engine consumes per km. Fuel consumption depends on a variety of factors, including:
- Engine type: A 1000cc petrol engine will use more fuel than a 1000cc diesel engine.
- Vehicle type: A car with a 1000cc engine will consume less fuel than a truck with the same engine size.
- Driving conditions: Driving in stop-and-go traffic uses more fuel than highway driving.
- Driving habits: Aggressive acceleration and braking increase fuel consumption.
- Vehicle condition: A well-maintained vehicle will use less fuel than a poorly maintained one.
To estimate fuel consumption, you can consult the vehicle's owner's manual or use online fuel economy calculators. These tools typically require information about the engine size, vehicle type, and driving conditions.
Remember, fuel consumption is a complex issue, and there is no single answer that applies to all 1000cc engines.
