Before going further with the discussions about the targets of automobile industries, first let’s discuss about the concepts of gas engines and diesel engines. According to the theoretical point of view, both diesel and gasoline engines are internal combustion engines. They both are designed to turn the fuel’s chemical energy into mechanical energy. Both converts fuel into energy through the series of small explosions or combustions. But in practical, diesel engines and gasoline engines are quite different. The major difference between both is hidden in the way that explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and then ignited by spark plugs. But in a diesel engine, first the air compression happens and then the fuel is injected.

Targets of automobile industry at present
Nowadays, the modern automobile industry has engineers that are engaged to design the fuel-saving technologies. The new standard of fuel-economy is aimed to hit the targets which need automakers to double the average miles per gallon of vehicles which is going to hit 54.5 by 2025. It means, when you buy the cars for next time, it will definitely be the chance to get turbocharged and small engine car with more advanced driving features which cut the risk of accidents on roads.

From Ford Eco Boost engine to Chrysler’s nine-speed transmission, automobile companies are aimed at making more fuel-efficient passenger and heavy-duty vehicles. Now, it’s time to point out the focal points of the cars on which automobile companies are aimed at. The decline is projected to carry on in the United States with the increasing demand of gasoline. Some refineries have been closed in Pennsylvania and the Virgin Islands of US in recent years.
Pushing to 54.5 mpg
Today, the automakers are focusing on the new standards of fuel economy. On these standards, they are rushing to double the fuel-economy targets up to 54.5 mpg by these ways:
1. Alternate fueling: The alternate charging and fueling stations are becoming more practical for the motorists and the auto dealers. They are dealing to make the cars that can run by natural gas, hydrogen cells, electricity, or diesel.
2. Weight reduction: the automakers are also making the light weight cars. They are installing the lightweight plastic parts that will cut the weight to take less power by the engine.
3. Engine: Generally the modern engines will pack more power in few cylinders that reduces burning of fuel, weight and friction. The turbocharged and supercharged engines will become capable to use more horsepower with less fuel-burn.
4. Automation: With this technique, the engines will automatically turn off while idling and downhill driving. Cars will slow down automatically when detecting the red signals in order to avoid sudden braking which reduces fuel-efficiency.
5. Transmissions: In future, some cars will improve themselves with eight or nine-speed transmissions while some will be improved with gearless. The transmissions will eventually adjust with the optimal engine speed-wheel ratio.
6. Aerodynamics: The rounder ends at the front and grille shutters will automatically adjust with the temperature of vehicle and cut down the speed on air resistance.

Why we shall opt for used motors?
The engine is the main part of a passenger vehicle as we all know. If your vehicle has diesel engine, it is said to be very expensive part. When it comes to replace an engine urgently, it is good to replace it with used one. It is not just about your budget, in fact it is about your environment. A lot of used auto parts stores have been opened to serve the vehicle owners. You can either search for the used parts in the market or in the online stores.
