The cars based on diesel engined compared to petrol engines are more powerful, it is not surprising that the current market appetite switch to diesel cars with all the advantages that exist in the diesel-engined cars. These fact have brought new competitor in diesel engine based cars, including bmw, jaguar, etc. which have made special type of their sedan saloon car with diesel engine. As for strength and duration this kind of type is quite favorite and as you could see in bmw leasing.

The main reason is the increasing price of fuel that inevitably force consumers to use a car with a fuel that is cheaper or even leave the conventional cars and switch to hybrid cars. Diesel cars with diesel fuel are more efficient than gasoline cars. But how about the pollution between diesel and gasoline cars, is it higher in diesel? Lets have a look below and break the myth about diesel engine based cars.

Eco-driving or economic driving, its time to pay more attention on environment we live. We all know that fossil resources for making fuels will run out eventually, other than that pollution that being contributed mostly from our vehicles are very concerning. Not to mention that the numbers of vehicle kept on increasing each years.

Although we do know that fuels could be produced from chemical mix or bio-fuels, and its reducing the amount of pollution, but at the end it would be more better if we do eco-driving as well.

Hybrid vehicles achieve reduced fuel consumption by incorporating in the drive train, in addition to an internal combustion (IC) engine, both an energy storage device and a means of converting the stored energy into mechanical motion. Some hybrids are also able to convert mechanical motion into stored energy. In its most general sense, the storage device can be a battery, flywheel, compressible fluid, elastomer, or ultra capacitor.

The means of converting energy between storage and mechanical motion is through the use of one or more motors/ generators (e.g., electric, pneumatic, hydraulic). In motor mode, these devices convert stored energy into mechanical
motion to propel the vehicle, and in generator mode, these devices convert vehicle motion into stored energy by providing part of the vehicle braking function (regeneration).

Light-duty compression-ignition (CI) engines operating on diesel fuels have the highest thermodynamic cycle efficiency of all light-duty engine types. The CI diesel thermodynamic cycle efficiency advantage over the more common SI gasoline engine stems from three major factors: the CI’s use of lean mixtures, its lack of throttling of the intake charge, and its higher compression ratios. In a CI diesel engine-equipped vehicle, there is an additional benefit of reduced volumetric fuel consumption (e.g., gal/100 miles) because diesel fuel provides more energy per gallon than gasoline.

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.
