Nowadays, technology always improves, time doesn’t stop and people are creating more and more stuff to build our world more efficiently. Cars are like a casual thing in today world, most people in the world own at least one car. But there is a problem, or a chance we can make our life better, because we know the gas is expensive, and there are more and more ideas coming out to improve the car to be more efficiency, to use less gas, or to have more gas mileage.

Besides a smaller, more efficient engine, today’s hybrids use many other tricks to increase fuel efficiency. Some of those tricks will help any type of car get better mileage, and some only apply to a hybrid. To squeeze every last mile out of a gallon of gasoline, a hybrid car can Recover energy and store it in the battery, Sometimes shut off the engine, Use advanced aerodynamics to reduce drag, Use low-rolling resistance tires, and Use lightweight materials.

Also, as I found the resources online, the engine could boost fuel economy by half, a major parts supplier to automakers, Delphi, is developing an engine technology that could improve the fuel economy of gas-powered cars by 50 percent, potentially rivaling the performance of hybrid vehicles while costing less. A test engine based on the technology is similar in some ways to a highly efficient diesel engine, but runs on gasoline.

His company has demonstrated the technology in a single-piston test engine under a wide range of operating conditions. It is beginning tests on a multi cylinder engine that will more closely approximate a production engine. Its fuel economy estimates suggest that engines based on the technology could be far more efficient than even diesel engines. Those estimates are based on simulations of how a mid-sized vehicle would perform with a multicylinder version of the new engine.

The Delphi technology is the latest attempt by researchers to combine the best qualities of diesel and gasoline engines. Diesel engines are 40 to 45 percent efficient in using the energy in fuel to propel a vehicle, compared to roughly 30 percent efficiency for gasoline engines. But diesel engines are dirty and require expensive exhaust-treatment technology to meet emissions regulations.
