Vehicle manufacturers are adding energy-efficient technologies such as turbochargers to their products to meet Canada’s increasingly stringent greenhouse gas emission standards for light-duty vehicles.
Using a smaller, turbocharged engine can lower fuel consumption by 2 to 6%. This saves you money and reduces your impact on the environment.
Turbochargers boost the power of smaller engines
Turbochargers force air into an engine’s cylinders – unlike a standard engine, which draws air in at atmospheric pressure. This means that a smaller, turbocharged engine can produce the same power as a larger standard engine.
Turbochargers use the otherwise wasted energy from the exhaust to drive a turbine that is attached to a compressor.
The compressor forces air into the cylinders of the engine. This provides two benefits. First, more air and fuel means a larger combustion reaction and more power. Second, the pistons have less work to do pulling the air-fuel mixture into the combustion chamber.
How much a turbocharger can save
Over 10 years, a turbocharger can save you $240 to $1,680 in fuel costs and lower your carbon dioxide (CO2) emissions by 550 to 3,860 kg. At the high end, this is equivalent to
- three quarters of an Olympic-sized swimming pool of CO2
- removing a mid-size car from Canadian roads for one year
- nearly 20% of our annual per capita emissions in Canada, which is 22.1 tonnes
