The term «engine braking» refers to the braking effect that occurs
in gasoline engines when the accelerator pedal is released.
Porsche is the only automaker using two turbos with variable turbine
geometry in a gasoline engine, and the newest Turbo S uses different engine hardware for the first time — in this case, larger turbo impellers and a modified housing, enabling a higher 7,200 rpm redline.
The 2.7 - liter EcoBoost engine features the first use of a compacted graphite iron cylinder
block in a gasoline engine, the same material used in Ford's 6.7 - liter Power Stroke turbo - diesel V8 engine.
The team at Air Fuel Synthesis (AFS) has created a system for using renewable energy to power the capture of CO2 and water, which is then transformed into liquid hydrocarbon fuels that can be used
directly in gasoline engines.
I'm specifically referring to the loss due to the pistons pulling air through a mostly closed throttle while cruising at highway
speeds in a gasoline engine.
A1 / B1 Stable, stay - in - grade oil intended for use at extended drain
intervals in gasoline engines and car & light van diesel engines specifically designed to be capable of using low friction low viscosity oils with a high temperature / high shear rate viscosity of 2.6 mPa * s for xW / 20 and 2.9 to 3.5 mPa.s for all other viscosity grades.
I've read gasoline engines use sparks to ignite the mixture, but diesel engines use just compression which can't be
done in gasoline engines due to high compression ratios which can cause engine knocking, but if that was true gasoline?
I've been mostly driving / working on diesels for the last 15 years or so, so I'm loosing touch with what goes
wrong in gasoline engines.
Back in the gasoline engine's favor, the Endurance - powered XD is $ 5,000 less expensive across the board compared with the diesel of the same trim level, and is 500 pounds lighter and, consequently, has 500 pounds more payload capacity for those who prefer to haul heavy items in the bed versus tow.
Throttle-less
operation in gasoline engines - Control intake valve lift, remove the throttle and improve part - load fuel economy from reduced pumping losses.
Customers
interested in gasoline engines will have a base version powered by a 1.2 TFSI engine that generates a total of 105 HP and 129 lbs - ft of torque.
* Hands on
experience in gasoline engine control systems, ISO 26262 / Functional safety, engine calibration and performance testing, HIL, MATLAB, Embedded C, MotoHawk, MotoTune, Kvaser Canking, CANalyzer.
The 2.7 - liter EcoBoost engine also features Ford's first use of a compacted graphite iron cylinder
block in a gasoline engine, the same material used in Ford's 6.7 - liter Power Stroke ® turbo diesel V8 in Super Duty trucks.
(*) Diesel fuel is not
used in a gasoline engine, so its low octane rating is not an issue; the relevant metric for diesel engines is the cetane number
In the gasoline engine, Twin Power tech consists of High Precision Injection with direct fuel injection, VALVETRONIC variable valve control and double VANOS variable camshaft control.
In a gasoline engine, this power loss is much more pronounced.
