Gas/Electric-Hybrid Engine

A Gas/Electric Hybrid Engine combines an electric engine component with a conventional internal combustion engine that burns gasoline. The Toyota Prius is a common example of a car that features a gas/electric-hybrid engine. These types of vehicles offer better fuel economy than traditional cars because the engine isn’t powered exclusively by gasoline. Regenerative braking, which converts the vehicle’s kinetic energy into electric energy essentially “recycles” energy that recharges the battery without wasting gas. This kind of car also reduces emissions because little exhaust escapes when the car is idling.

Gasoline Engine

A Gasoline Engine is a traditional internal combustion engine designed to run on gasoline. Invented in 1876, this engine continues to power most vehicles in the U.S., but due to the political impact of buying foreign oil and the high cost of gasoline, many automakers now offer hybrid engine and all-electric vehicles to meet the increasing demand for alternative engines.


Gasoline is a petroleum-derived oil used in internal combustion engines. It is designated with an octane rating. A higher octane rating translates to a higher compression ratio. This provides for better power output and is the reason sports cars require maximum octane gas.


A Gasket is essentially a seal between two mechanisms. On your car, the head gasket plays a vital role by sealing the combustion process so that oil and coolant do not mix in the combustion chamber. Overheating, coolant leaks, white smoke exhaust and residue on your oil dipstick can be indicators of a “blown head gasket.”


A Gear is a rotating part that has a cut-tooth edge designed for meshing with another tooth-edged part in order to transmit torque to a mechanism. Gears can change speed, torque, and the direction of a power source. Whether you have a manual or automatic transmission, the gears on your car move you forward and backward, faster and slower.

Gear Oil

Gear Oil is a high-viscosity oil designed to lubricate the gears of your car so that they move freely without undue friction.

Gear Ratio

Gear Ratio determines the amount of torque that can be delivered to a mechanism. The higher the gear ratio, the higher the torque output; higher torque results in greater speed.


Early cars used a generator to power the battery. Today, alternators power the battery in lieu of a generator so that the battery power does not deplete at a continuous rate.


Glazing is when the belts starts to slip. The alternator belt slipping slows down the engine, causing it to stall. Once this starts to happen, you will only be able to restart your car a few times using battery power before the belt fails entirely and depletes all of your battery power.
