Unless your car drives on alternative fuel (more on these later), you’ll typically see three types of gas at your local gas station. They're distinguished by their octane rating, which serves as a measure of a fuel’s stability. The higher the octane rating, the greater the pressure the...
Many people continue to use cars and motorcycles even though they know that they are bad for the environment. Why is this the case? What can be done to reduce the use of these vehicles? Give reasons for your answer and include any relevant examples from your own knowledge or experience. ...
When it comes to Electric Vehicles (EVs), the options go well beyond those powered only by batteries. Car purchasers can now choose from a variety of choices, including those that use fuel cells or combine a gas engine in hybrid and plug-in hybrids. In this blog, we’ll discuss four va...
Features like gas mileage, touchscreen size, heated seats and lumbar support can also be important to consider. Of course, newer vehicles are also equipped with a number of innovative safety features that can prove priceless. Even if you’re not thinking about buying a new vehicle for awhile...
DC Motors–DC (direct current) motors have been around for a long time and were the first type of motor used in electric vehicles. They are reasonably priced, have a straightforward design, and have strong torque at low speeds. However, because they have brushes and commutators, DC motors ...
Plug-in Hybrid Electric Vehicles (PHEVs) combine both electric and gasoline or diesel power. The way it does this is based onthe drivetrain, which creates three sub-classifications of PHEVs: • Series: Uses a gas engine to charge the electric battery, meaning the vehicle’s movement is en...
Pros:More fuel efficient than ICE vehicles, range is limited only by size of gas tank. Cons:Requires gasoline and oil, generates tailpipe emissions. . Plug-in Hybrid Electric Vehicles (PHEVs) Like an HEV, a plug-in hybrid electric vehicle uses a combination of an ICE and a battery pack...
In the wake of the 1973 oil crisis, the replacement of traditional petroleum-based fuel with a petrol bioethanol hybrid commenced. Purified bioethanol is unsuitable with standard spark-injection combustion engines, necessitating the use of engine modifications or flexible-fuel vehicles. Forecasts for ...
Mild hybrid electric vehicles pair an ICE with a small battery that provides added electric power to help reduce the gas engine’s workload. In turn, the benefits of an MHEV include improved fuel economy, increased performance, and enhanced passenger comfort. In addition, regenerative...
【题文】With nearly a quarter of global greenhouse gas coming from all types of transportation, can we keep ourselves off gas-powered vehicles to avoid the worst effects? As more governments push for urgent action on climate change, quite a few companies are betting their future – that millio...
