A funny car is a type of drag racing vehicle and a specific racing class in organized drag racing. Funny cars are characterized by having tilt-up fiberglass or carbon fiber automotive bodies over a custom-fabricated chassis, giving them an appearance vaguely approximating manufacturers' showroom models.
Hydraulic lifters were nearly universal on cars designed in the 1980s, but some newer cars have reverted to bucket-and-shim mechanical lifters. Although these do not run as quietly and are not maintenance-free, they are cheaper. [citation needed] Nearly all modern non-hydraulic lifter arrangements are on overhead cam engines.

Rochester Ramject as seen on 1959 Chevrolet passenger car In the early 1950s, fuel injection was the topic of a significant amount of research by the auto industry in the US and internationally. Ed Cole , who had become the chief engineer of Chevrolet in 1952, pushed for Chevrolet to be the first GM brand to offer a fuel injection option on a ...
Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. [1] In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced ...
A jet injector, also known as a jet gun injector, air gun, or pneumatic injector, is a medical instrument that uses a high-pressure jet of liquid medication to penetrate the skin and deliver medication under the skin without a needle. Jet injectors can be single-dose or multi-dose.
[8] [9] Stock car racing technology had fallen behind the technology used in vehicles that are mass-produced for the general public. The reason behind this is that NASCAR didn't take advantage of fuel injection when fuel injected vehicles started to almost completely replace carburetor-powered vehicles during the late 1980s.
An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts except a valve to control inlet flow.
A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and cooled by the fuel itself.
