Using units of MJ per kilogram, the net heating values of petrol, diesel, LPG and CNG are about 45, 43, 46, and 44; the net heating value does not include the heat in the water vapor of the combustion products.
Diesel fuel does not evaporate as easily as gasoline, so it is much safer in accidents. There is a reason diesel engines are favored in the commercial transportation energy: Although manufacturers today are getting pretty good at using sound-deadening insulation in their cars, diesel engines still have a bit of that characteristic diesel clatter.
In the case of petrol and LPG the vapors given off is heavier than air and will tend to pool near the ground. Weighing both sides will help you decide whether you should go for a diesel car or not. These cylinders are manufactured and tested in compliance with strict regulations, and have withstood severe abuse testing under conditions far more stringent than tanks designed for storing gasoline.
Is it worth it to get a car that runs on diesel. Diesel fuel and exhaust just smells better. Diesels are better in remote areas and third world countries because they can run on vegetable oil and are less complicated than other drivetrains.
So to avoid high costs of hiring a mechanic, the best thing to do is to make sure your diesel vehicle gets checked up regularly.
One of the main benefits of choosing diesel in the past was that it was cheaper than gasoline. In fact, we use more gasoline than the rest of the world-combined. Diesel has history on its side. EmissionsNatural gas is the cleanest burning alternative fuel.
As per my research says, petrol is comparatively a best option in compare to CNG as it is offers you affordability along best attractive features. Geographically it is found beneath earth surface that later on passes through refinement process which leads to the formation of different types of fuels.
For instance, CNG Vehicle emissions of carbon monoxide are approximately 70 percent lower, non-methane organic gas emissions are 89 percent lower, and oxides of nitrogen emissions are 87 percent lower. The trucking industry uses diesel fuel. CNG Vehicles also emit very low levels of carbon monoxide approximately 70 percent lower than a comparable Petrol vehicle and volatile organic compounds.
Less waste heat equals more horsepower through greater efficiency. In the US a survey was taken of more than 8, vehicles that cumulatively traveled approximately million miles from Natural gas is a clean-burning fuel that reduces vehicle maintenance.
Diesel engines are like garbage disposals-they'll eat any type of oil-based fuel.
The next highest efficiency in the fuels comes from CNG, which can operate at say. CNG CAN BE THE BEST ALTERNATIVE TO PETROL AND DIESEL INTRODUCTION ADVANTAGES Affordable Price Environmentally friendly Fuel economy As the world continues to experience high costs of gasoline, the low price of CNG offers a glimmer of hope Considering the price of gasoline in India, which costs Rs/liter (even though being largely government subsidized), in comparison to CNG.
Article on advantages, benefits, and reasons for considering diesel powered generators or engines.
How diesel engines work, common uses and applications, benefits, and more. Article on the fundamentals of diesel engines. Learn about the history, advantages, and applications of the diesel powered engine.
There are multitudes of advantages of using CNG in your vehicle over conventional fuels like Petrol/Gasolene and Diesel. However, the alternative does come at a price. The performance of the car is reduced significantly. Due to its gaseous form, it is required to be stored in a higher pressure tank of bars.
If you would compare its energy density, then you would discover that its density is 25% in compare to diesel and 42% in compare to LNG.
These two features are considered to be a great disadvantage of CNG. Most of them refusing to buy a diesel car because it is heavier, more smoke producing, funny smelling, noisier with vibration and costlier than petrol powered ones.
Petrol Engine powered vehicles Pros/Advantages. It is Cheaper than a diesel car to purchase. You have Less noise and vibration than a. Advantages of CNG It is the most economical & environment friendly fuel available. Though the initial cost of conversion kit may seem to be high, the same can be recovered in less than 2 years because of low operating cost.Advantage of cng over petrol and diesel cars essay
