The objective of knock control strategies is to attempt to optimize the trade-off between protecting the engine from damaging knock events and maximizing the engine's output torque. Knock events are an independent random process. [8] It is impossible to design knock controllers in a deterministic platform. A single time history simulation or ...
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel.
Tire warning light on a car dashboard. But in cold weather, the TPMS may trigger a warning because of something completely natural. The air inside a tire condenses in colder weather, taking up ...
A typical engine coolant radiator used in an automobile. Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine.
A growing number of countries have drawn up plans to ban leaded gasoline in the near future. Some experts speculate that leaded petrol was behind a global crime wave in the late 1980s and early 1990s. [8] To avoid deposits of lead inside the engine, lead scavengers are added to the gasoline together with tetraethyllead. The most common ones are:
Several changes were also made under the hood. An engine knock sensor and revised engine tuning increased horsepower and torque ratings for the 2003 CVPI to 239 hp and 287 lb-ft of torque. Additionally, the entire exhaust system was re-designed, with exhaust hangers now mounted to the frame rails; this allowed for a reduction in interior noise.
