Fuel economy is a big role in determining how clean engines run without polluting the environment right? Diesels are known to have excessive levels of smelly emissions when compared with gasoline-powered cars, because diesel is extremely greasy and does not evaporate like gas emission. It 's a known fact that diesel cars are still lagging behind in terms of Nitrogen Oxide emissions, which makes gasoline cars more environmentally friendly than diesel cars but they can’t be perfect. Another con of diesel cars is that they make a ton of noise opposed to gasoline cars. There are ways to reduce the noise of the car, but diesel engines are still louder and vibrate more than gasoline cars and would take away from that power.
Hybrid, electrical, and hydrogen fuel cell cars have performance property and what these have pros and cons, development current situation, and problem. Today, Hybrid cars are popular. Hybrid car works on a combination between electric and fuels. The engine powered by oil and that of the engine support by an electric charge. Engine is used to move the car, only when electric motors are extremely slow and measured speed.
These cars operate from a rechargeable battery and gasoline. The engines are smaller so that they will be able to accommodate the 99% of time when the car is not going uphill or accelerating quickly. The battery is used to give extra acceleration power if needed. When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery. These cars are aerodynamic and the tires are often stiffer and inflated higher to reduce dragging.
It is often the case we have to buy cheap second hand cars as new cars are very expensive. Sometimes this is fine and you can have a reliable car, but other times you pick one up that’s not been well maintained and can cost you a fortune in repairs and keeping it on the road. Petrol prices generally go up, rarely coming down even when global fuel prices go down. This is an ongoing expense too, a car is useless without fuel. Picking a car with a smaller engine can save fuel and modern cars also have been designed with better fuel economy, but as I have already mentioned modern cars cost more money upfront.
However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries. Electric cars are becoming increasingly more necessary, and have more advantages than disadvantages. Electric cars help to decrease the noise, pollution as they are much quieter.
In order to have a fast and efficient car all these things I have discussed need to be taken into consideration. A fast car should be designed with aerodynamic surfaces for a balance of maximum production of downforce and minimum drag creating surfaces. It should have as small an engine as possible to reduce mass and reduce the necessary size of the frontal area, but a large enough engine to be able to produce enough horsepower to be able to create more force than the resistance the car faces to accelerate and enough to balance with those forces at high speeds. The tires should be wide enough for fast acceleration and good cornering but not so wide it creates large amounts of rolling resistance. Your overall best example of such a car would be formula one races or Indy cars because they have to have good handling, fast acceleration and reach and maintain high speeds.
Johnchang K. (2013) suggests that car of the future is hybrid cars. It is considered, that gasoline fuel is used more effectively and toxic fumes are reducing number of harmful emissions into the atmosphere. Nowadays, hybrid cars become popular day by day because of these advantages and gasoline engine cars are unclaimed by more people, because purchase of hybrid cars are reducing of fuel prices. (20) However, besides some advantages this item has also several disadvantages. The aim of this report will try to analyse the main problems of hybrid vehicles which are faced by engineers and car manufacturers in modern society.
New cars can be classified into three main categories, which are normal cars, luxury cars and inferior cars. For inferior cars such as the Volkswagen cars, when real income is rising, that is pay is increasing faster than inflation, people are likely to demand less of them and a fall in income leads to an increase in demand for them (Boundless:2013). They have a negative income elasticity of demand. Normal new cars have positive income elasticity of demand. An increase in income leads to an increase in demand for them and a fall in income leads to a fall in demand (Gillespie: 2011:71).
Hybrid Prius A hybrid car is a car which can run on two or more fuel sources. A Hybrid Prius is a vehicle that is fuel efficient with two motors. At low speed it runs on an electric motor powered by a battery pack, and at higher speed it runs by a gasoline engine. The two engines share work. This helps reduce the amount of gasoline-power energy required to move the car.
It takes more gas to fill up these vehicles, and the big engines consume it as if they’re where no tomorrow. The weight of the vehicle also contributes heavily to this consumption since it needs to burn more fuel to drive it. The sports utility vehicle harms everybody with all of its emissions that it emits into the environment. However, driving a car does not bring the emissions as high. The smaller engines and the lightweight of cars make them a Low Emissions Vehicle (LEV).
