Diesel engines are typically well suited to turbocharging due to two factors: A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture.
A turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, increasing pumping losses. [ 52 ] Supercharged engines are common in applications where throttle response is a key concern, and supercharged engines are less likely to heat soak the intake air.
You’ve heard the hypothesis before: Turbocharged cars miss their advertised fuel-economy figures more often and by larger margins than naturally aspirated cars. It’s a notion repeated so often ...
By the mid-1980s, turbocharged engines dominated Formula One, until they were banned after the 1988 season. Turbochargers returned to Formula One for the 2014 season, with turbocharged 1.6 L (98 cu in) V6 engines replacing the naturally aspirated 2.4 L (146 cu in) V8 engines that were previously used. The turbocharging combined with more ...
We test two pairs of turbocharged and naturally aspirated vehicles to quantify the price of progress. As Turbocharging Takes Over, Some Types of Vehicles Stand to Lose More Than Others Skip to ...
The 12N360 is a turbocharged, horizontal X engine with 12 cylinders. The X design makes it much more compact than its predecessor, the V-93 [ 2 ] ( Chelyabinsk Tractor Plant ), and similar in size to the 5TDF [ 3 ] and 6TDF two-stroke opposed-piston engines ( Malyshev Factory ).
Whether you're buying a new or used car, it's no small decision. Cars are expensive. In fact, according to a AAA 2023 study, the average annual cost to own a car is $12,182. That includes, car loan...
Recently diesel engines became able to outperform similar-sized petrol engines. Most naturally aspirated gasoline engines have better responsiveness than supercharged or turbocharged engines for engines with similar peak power outputs. However, factors such as improper maintenance, fouled spark plugs or bad injectors can reduce throttle response.
