When it comes to performance, there are many different terms that are used to describe various powertrain types. However, the best one for superior output is a motor that comes with direct injection technology. But what exactly does that mean? This article will explain all about it!
As we have covered in previous posts, engines are made up of cylinders that are comprised of valves and pistons. When the pistons move up and down, combustion occurs which generates horsepower. When a direct injection system is added into the mix, nozzles are placed inside the chamber of every piston.
These components then spray a fine mist of gasoline at a higher pressure - coating the interior of the combustion chamber. This system precisely measures the amount of fuel injected much more efficiently than old school carburettors or fuel-injector systems.
So why go through all of this trouble? The aforementioned process allows the combustion cycle to be completed with cooler temperatures inside the cylinders. This results in a higher compression ratio which then leads to more power and enhanced fuel efficiency. On average, a direct injection system can ramp up the estimated mileage by 15 percent and the total torque output by 50 percent.
