The central locking in a car operates using a manual system, a remote keyless system or a combination of both. A manual system involves the ability to lock all doors of a car, including the tailgate, by manually pressing a button. A remote keyless system operates in the same manner using a remote control that functions similarly to a television remote control.Know More
The central locking system can access all doors, the tailgate and even the fuel lids. All central locking systems operate using an electro mechanical system that can be divided into the following subsystems: the remote control, which operates using either a coded infrared or radio frequency signal, the electric control module, which is the unit responsible for signal processing and the actuator.
The actual locking and unlocking of the central locking system is done by the actuator. There are two different types of actuators that can be installed in cars. They are:
A car cigarette lighter consists of a coil of nichrome wire heated until it glows by a strong electrical current. When the driver pushes in the cigarette lighter, it presses the device into an electric receptacle, allowing the current to heat the coil. Once the lighter is hot, a metallic strip bends away, allowing the device to pop back out for use.Full Answer >
The oxygen sensor is positioned inside in the exhaust pipe, and it is used to detect rich or lean mixtures. This sensor is an essential component in the emissions control system, and it transmits data to the engine's computer. The primary function of the oxygen sensor is to help the engine operate as smoothly as possible by detecting the appropriate air-to-fuel ratio and using fuel efficiently.Full Answer >
If a car horn is not working properly, its fuse, siren or button may be damaged. Before the horn can be fixed, the vehicle will need to be diagnosed properly.Full Answer >
A car immobiliser disables one of the systems needed to start a car's engine, usually the fuel supply or the ignition. This is accomplished by RF identification between a transponder in the ignition key and a device called a RF reader in the steering column. The transponder sends a signal with a unique identification code to the reader, which relays it to a receiver in the vehicle's computer control module.Full Answer >
