Sentences with phrase «engine friction loss»

Those help generate a 30 percent reduction in engine friction loss, Subaru said.

Not exact matches

This also limits the maximum RPM of the engine because there are increased friction losses due to increased speed of the piston at the same RPM when compared to an engine with less stroke.

And although a turbo engine can't have the super-high compression ratio of Mazda's naturally aspirated Skyactiv engines, it boasts 1.6 times less mechanical loss as a result of less internal friction.

Infiniti says the variable combustion ratio mechanisms and related hardware increases VC - T engine's weight by about 22 lb compared with a regular inline 4, and that friction losses are similar to those in a four - cylinder engine with a balance shaft.

Although this smaller - displacement turbo four - cylinder has lower internal friction and reduced pumping loss than a Skyactiv V - 6 would, fuel efficiency drops when the engine is under high load, as the engine runs richer to help keep the cylinders cooler.

Traffic regulations in a large number of countries require trucks to always drive with an engaged gear, which in turn provides a certain amount of engine braking (viscous losses to the engine oil and air pumped through the engine and friction losses to the cylinder walls and bearings) when no accelerator pedal is applied.

Turbocharging can improve the fuel economy [88] of diesel engines by recovering waste heat from the exhaust, increasing the excess air factor, and increasing the ratio of engine output to friction losses.

In the manual transmission - equipped 86, this engine reduces friction and pumping loss, helping to provide an optimized power curve.

To reduce friction loss in the engine, pistons in the 1.8 litre engine have a molybdenum treatment applied in a polka - dot pattern.

How can you get better engine efficiency or better mileage with a CVT with more transmission friction loss than dual clutch units?

I should correct one thing: the increased low - end torque from the turbo / DI combination also allows more driving to be done without downshifting, which downspeeds the engine and reduces friction losses.

The advantages of downsizing include improved efficiency through reduced internal friction, lower pumping losses, and lighter weight — which also makes the engine warm up more quickly.

Measures to reduce friction losses and thus help enhance engine efficiency include the adoption of narrow, lightweight roller rocker arms and low - friction timing chains, while D - 4S direct fuel injection helps create optimum combustion conditions, contributing to enhanced fuel efficiency.

Friction loss has been cut by approximately 20 % compared to the current engine (when running at 50km / h).

While the compact combustion chamber and higher compression ratio on gasoline engine helps to improve engine efficiency, the advanced thermal management system in diesel engine along with low friction engine oil and modified fuel injection system help diesel engine in faster warm up and lower frictional losses.

Other innovations have reduced intake / exhaust system losses and valvetrain friction, contributing to improved engine performance.

This engine produces 170 hp and 175 lb - ft of torque — a carryover from the outgoing model — with the latest version of the CVT achieving a 40 percent reduction in friction loss, as well as gaining a wider gear ratio and greater efficiency compared to earlier units.

High efficiency is achieved with new engine technologies such as multi-hole injectors, cavity pistons, dual sequential - valve timing (S - VT) and reduced friction and pumping losses.

Several measures have been adopted to reduce friction losses within various parts of the engine, enhancing fuel economy.

Measures to reduce friction losses and thus improve engine efficiency include the adoption of narrow, lightweight roller rocker arms and low - friction timing chains, while D - 4S direct fuel injection helps create optimum combustion conditions, contributing to enhanced fuel economy.

After the cold start the engine is temporarily fully uncoupled from the cooling circuit, considerably shortening the warm - up phase with its high loss of friction.

In EV Drive operation, when the battery - powered drive motor is used for either acceleration or regenerative braking, a clutch disengages the stopped gasoline engine from the drivetrain to eliminate efficiency loss from mechanical friction in the engine.

A new high - pressure injection system and continuously - controlled variable oil pump reduce friction losses in the engine, with the lower powered 110 ps version available across both the standard cee'd and new GT Line range.

A combination of these with other technologies, including materials substitution, reduced aerodynamic drag, reduced rolling resistance, reduced engine friction and pumping losses, has the potential to approximately double the fuel economy of «new» light - duty vehicles by 2030, thereby roughly halving carbon emissions per vehicle mile travelled (note that this is only for a new car and not the fleet average)(medium agreement, medium evidence)[5.3.1].
