Compressed natural gas CNG vehicles operate much like gasoline-powered vehicles with spark-ignited internal combustion engines. The engine functions the same way as a gasoline engine. Natural gas is stored in a fuel tank, or cylinder, typically at the back of the vehicle.

How Do Natural Gas Vehicles Work?

Engine cycles in which the effective compression ratio is smaller than the effective expansion ratio see compression ratio discussion under Engine Fundamentals can be referred to as over-expanded cycles.

After multi-valve technology became standard in engine design, Variable Valve Timing becomes the next step to enhance engine output, no matter power or torque. As you know, valves activate the breathing of engine. The timing of breathing, that is, the timing of air intake and exhaust, is controlled by the shape and phase angle of cams. To optimise the breathing, engine requires different valve timing at different speed. When the rev increases, the duration of intake and exhaust stroke decreases so that fresh air becomes not fast enough to enter the combustion chamber, while the exhaust becomes not fast enough to leave the combustion chamber.

Variable valve timing

In internal combustion engines , variable valve timing VVT is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing [ citation needed ] many automotive manufacturers to use VVT systems. Two-stroke engines use a power valve system to get similar results to VVT.

The engine valves are just like the human nose. Engine valve timing is the most critical process of IC engines. The inlet valve usually opens few degrees before the piston reaches TDC in its exhaust stroke.

Dejan on August 26, Hi. İ20 1. Hyundai i20 PB - , 4Cyl, Hatchback. The radio cd player packed upSome times if any problum is especially a fluid over brake disk in brakes then definitely it is an issue, other wise I didn't face any problem in I20 I don't think Hyundai i20 have any braking problem although I have verna fluidic but as my experience there must be some problem with your break padsRemove the timing chain oil jet A and the crankshaft chain sprocket B. Once the timing chain kit had been replaced and the engine rebuilt the car purred as it should. While that can be a costly repair package, preventative maintenance will save you thousands over time. The head of the valve could break and get stuck in the piston.

Light-duty compression-ignition CI engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. In a CI diesel engine-equipped vehicle, there is an additional benefit of reduced volumetric fuel consumption e. Lean mixtures, whose expansions are thermodynamically more efficient because of their higher ratio of specific heats, are enabled by the CI diesel combustion process. In this process, diesel fuel, which has chemical and physical properties such that it self-ignites readily, is injected into the cylinder late in the compression stroke. Ignition occurs following atomization of the fuel jet into small droplets that vaporize and mix, creating pockets of heterogeneous combustible mixtures.
