The share of diesel vehicles among new car registrations in the EU decreased from a peak of 55% in 2011 to 49% in 2016; recent data suggests that diesel shares continue to fall. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.

We expect the efficiencies to continue to climb as modifications are made and new simulations are conducted, including computer modeling of the 2011 Nissan Sentra running with a Scuderi engine. With turbocharging, we can have some huge gains, we can downsize the engine and produce very big power. —Sal Scuderi. —Sal Scuderi.

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Turbocharging and downsizing can also yield fuel consumption reductions. Downsizing is an important strategy applicable in combination with technologies that increase engine torque, such as turbocharging or supercharging. Part of the gain from advanced-level CI diesel engines comes from downsizing.

LSPI is considered an impediment to aggressive engine downsizing to reduce carbon dioxide emissions. The initial meeting for the Preignition Prevention Program Consortium is scheduled for January 2011. Under these conditions, a preignition event leads to very heavy knock, which can cause catastrophic damage in only a few engine cycles.

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.
