Time to time everything gets its upgrades because of inventors’ experiments. When new versions come to market, people would like to buy these to utilize. In automobile industry, there are various sides which are developing to make it comfortable. Motor engine is the main part of the vehicle. It’s like the human heart. Motor engines follow main several technologies. Latest and most effective one is hybrid technology. Thus hybrid vehicles have a big demand in the market currently.
The word ‘hybrid’ is defined as something that is a mixture of two very different things. Same as that, hybrid vehicle has two power methods to move the vehicle. The two methods are conventional internal combustion engine and high voltage electric motors. It can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools. The Lhoner Porsche Mixte hybrid was the first gasoline-electric hybrid automobile 1901.
There are two kind of hybrid. Those are series hybrid and parallel hybrid. In a series, hybrid the primary power source (internal combustion engine or fuel cell) drives a generator. The electric power from the generator is stored in batteries, and is used to power an electric traction motor that drives the wheels. Most true series hybrids in use today are medium-duty vehicles such as transit buses. During certain operating modes, the Toyota Prius and Ford Escape are Parallel Hybrids, but cannot be defined as either series or parallel. In a parallel system the primary energy source can drive a generator as in a series system but it can also drive the vehicle alongside (or parallel to) the electric traction motor.
The Honda Integrated Motor Assist (IMA) is an excellent example of a parallel hybrid drive system.
Some of the advanced technologies typically used by hybrid including, regenerative braking, electric motor drive and automatic start/shut off. In regenerative braking, the electric motor applies resistance to the drive train causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.
The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. Automatic start/shut off means automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.
Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, as power is delivered both via an internal combustion engine or electric motor and the rider’s muscles. Hybrid power trains use diesel-electric or turbo-electric to power railway locomotives, buses, heavy goods vehicles, mobile hydraulic machinery and ships. The statistic shows that the number of hybrid and electric vehicles is forecast to be 80.4 million in 2015 in the world.
Hybrid cars are much more fuel efficient than conventional vehicles. According to statistics the average mileage for a hybrid at 38.7 miles per gallon (16.5 kilometers/liter) compared with 26.7 (11.4 kilometers/liter) for a gas-only vehicle. They require far less gas to cover the same distance.
It is worth noting that the hybrid engine is likely to be more environmentally friendly than a fully electric design for the near future. This is became the majority of electricity is generated from dirty sources such as rather outdated coal-fueled plants. In these cases the newer engines of the hybrid cars are considerably more efficient and cleaner, so from an environmental standpoint a hybrid design is preferable to an electrical car that is actually, in effect, powered by coal.
The new generation of diesel vehicles offers lower emissions, high efficiency, and superior performance.
A growing number of vehicles can run on an 85 percent blend of ethanol, but finding E85 vehicles can be tricky.
Question internal combustion. Pure electric cars are here. The choice is limited for now, but high volume is coming.
Today’s gas-electric hybrids, like the Toyota Prius, are among the most fuel efficient and greenest cars among vehicles relying on internal combustion power. All-electric cars are cleaner and require no fuel, but hybrids still sell better having no “range anxiety,” as well as costing comparably less, and with ability to refuel at the gas pump.
Hydrogen-powered cars are slowly becoming a reality. Limited-production models are being offered to a handful of drivers.
Several carmakers have or are planning to introduce 100+ mpg-hybrids that can be plugged into the electric grid.
The best strategy for fuel efficiency is to downsize. And there are many stylish and sporty options.
A stop-start hybrid is the simplest form of hybridization, if one wants to classify it as a “hybrid” at all, or merely an aid to efficiency. Automakers are putting this technology not only on gas-electric hybrids, but even straight internal combustion vehicles to save fuel. The engine does not need to run at a stop, and the engines are engineered so restart does not adversely affect their lifespan.
