Like the 2.0 D - 4D engine, it also benefits from improved piezo - electric fuel injectors, operating at higher pressure — increased from 1,800 to 2,000 bar.

Meanwhile, the automaker said high - precision fuel injection with up to 2,900 PSI of pressure dispenses atomized fuel at ideal pressures and in perfect patterns.

Nissan Motor Co. says it has developed a new turbocharging system that provides improved torque and engine response at low speeds in city driving.Nissan says the new system will give a 2.5 - liter engine the same fuel efficiency as a 2.0 - liter engine and the same low - speed torque as a naturally aspirated 3.5 - liter engine.The new system will be introduced in new models for the Japanese market later this year.The system is based on what Nissan calls a «linear charge concept,» which allows boost pressure to rise gradually with acceleration, increasing on a linear level from low to high speeds.

I know that the high pressure fuel pumps have been a problem for these cars, but I thought a $ 60,000 car would at least come with a functioning fuel pump

In Germany between 900,000 and 1,000,000 metric tons of a fuel satisfactory for automobile - type engines is being produced by adding the gas hydrogen to these coal tars or to powdered coal in a stream of crude oil at elevated temperature and high pressure.

It is reasonable to assume that human CO2 emissions will continue to grow at a slightly higher level than population, despite the fact that there is considerable pressure on fossil fuels (economic as well as environmental) and the carbon efficiency of all nations is continuously improving (especially in the developed nations).

But, the atmospheric pressure is sort of high — e.g., a day on Venus is more like spending time atop a piston in a diesel engine at the top of the compression cycle where the fuel mixture explodes!

They too have the diurnal problem under control — and they talk about the very high temperatures and pressures they obtain being used in other process to produce liquid fuels, which solve all the intermittency and transport problems (at a cost).

Some of the key principles of Eco-Driving are: • Maintain engine speeds between 1200 — 3000 rotations per minute (RPM); • Change to higher gears between 2000 — 2500 RPM, and drive in top gears at lower speeds — the so - called «50 in 4th gear» driving style; • Try to anticipate more to avoid strong accelerations, decelerations, overtaking or aggressive driving; • Driving at speed limits and avoiding high speeds; • Add 10 % to standard tyre pressure; • Avoid using the air condition, or set at temperatures above 21Â °C; • Use your bike for short trips — starting your car when it is «cold» uses 300 % more fuel.»

Higher octane fuel can withstand that pressure, whereas lower octane fuel will ignite all at once and melt the engine.
