"Direct injection" refers to a method used in engines where fuel is injected directly into the combustion chamber. This allows for better fuel efficiency, increased power, and reduced emissions.
Full definition
In the European combined driving cycle, the
gasoline direct injection system improves fuel consumption by 10 % over the counterpart V6 gasoline engine with port injection and fully variable valve timing.
The car has a powerful 1500 cc common rail
direct injection engine that is capable of providing smooth performance.
With 4 valves per cylinder and a variable turbine geometry the common - rail
direct injection system of the new small diesel engine operates at a maximum injection pressure of 1600 bar.
The transmission control fully utilizes the benefits
of direct injection technology right up to the physical limits: the quicker engine response ensures that injection is suppressed with even more precision.
The 2.0 - litre
turbocharged direct injection petrol engines are powerful and refined and generate strong torque from low speeds, ensuring excellent launch performance and mid-range response.
This is in contrast to the currently available 2.3 -
liter direct injection gasoline engine which is rated at 260 bhp with a tad less torque at 280 lb. - ft.
Though its bore and stroke are unchanged, the DOHC 2.4 - liter four - cylinder is basically all new, and
features direct injection for the first time.
This engine is incorporated with an advanced
direct injection fuel supply system, which allows the hatchback to deliver a decent fuel economy under standard driving conditions.
This setup combines low - pressure port injection with high -
pressure direct injection for more precise computer control over fueling.
* CX — equipped with a new 3.0
L direct injection V - 6, premium cloth seats and 17 - inch wheels.
Other technologies have been introduced such
as direct injection with fuel pressure increased to 250 bar and a special combustion chamber design to optimize the air - fuel mixture.
Smaller engines also tend to be cheaper to build, which is crucial when you're working with expensive technologies
like direct injection and variable valve timing.
It's interesting that
direct injection produces high levels of PM emissions in both diesel and gasoline cars; but, port injection doesn't in gasoline cars.
Direct injection delivers fuel directly to the combustion chambers and permits a higher compression ratio, improving fuel efficiency.
The 1.5 - liter, DOHC 16 - valve four
gains direct injection, helping to boost output from 117 hp and 106 lb - ft to 130 hp and 114 lb - ft.
While the gains expected by other makers are lower, there's widespread agreement that
direct injection offers all internal combustion engines yet another new lease on life.
With the help of a common rail
based direct injection fuel supply system, this vehicle can return a decent fuel economy.
On average, just 8.1 litres * of fuel f lows to the combustion chambers
via direct injection per 100 kilometres.
It'll be interesting to see if these tiny little turbocharged
direct injection motors make it even half that far with as few problems.
The car shown was a five - door hatchback model, also debuting a new 2.0 - litre
direct injection inline - four engine.
This was enabled by the new eight - speed automatic transmission and a rear differential which complement the
V12 direct injection engine.
It's an inexpensive option to help perk up and maintain your gasoline
direct injection vehicle, especially if you've been noticing reduced engine power for no other obvious reason.
Direct injection means that fuel is injected directly into the engine combustion chamber under much higher pressure.
The B - cycle combustion process with
central direct injection represents a new level of efficiency among the RS models.
Currently direct injection of genes into the cancer mass is being attempted, but it is unlikely that it will work because all the cells must be hit, which is very unlikely.
Direct injection refers to the fuel being sprayed directly into the cylinder similar to the diesel instead of the fuel being sprayed in on top of the intake valve like most regular gasoline engines.
