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.

In spite of the significant progress that battery technology has experienced in the last 20 years, the battery is still the most challenging technology in the design of hybrid vehicles.

All production hybrid vehicles used batteries employing nickel-metal-hydride (NiMH) chemistry. It is anticipated that the NiMH battery will be replaced by Li-ion batteries in the near future. The acceptability of today’s hybrid vehicles has been shown to be strongly dependent on the price of gasoline, as evidenced by the rapid growth of hybrid sales in 2008, when gasoline prices were high, and the fact that hybrid sales dropped dramatically in early 2009 when prices returned to lower values.

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.

The terms fuel economy and fuel consumption; these two terms are widely used, but very often interchangeably and incorrectly, which can generate confusion and incorrect interpretations:

Fuel economy is a measure of how far a vehicle will travel with a gallon of fuel; it is expressed in miles per gallon. This is a popular measure used for a long time by consumers in the United States; it is used also by vehicle manufacturers and regulators, mostly to communicate with the public. As a metric, fuel economy actually measures distance traveled per unit of fuel.
