Neutral Safety Switch Test Working of car neutral safety switch Helpful Information The functionality of the neutral safety switch has changed greatly through the automotive development era, what was once a simple switch for the reverse lights and starter safety circuits, this switch has now become a multifunction gear position sensor which provides feedback data to the body and engine computers, all related functions are then carried through the operating system. The neutral safety switch disables the starter operation when the vehicles transmission is not in neutral or park, and are equipped on automatic transmission vehicles only. A standard transmission car utilizes and clutch safety switch in place of the neutral safety switch which accomplishes the same objective. When a neutral safety switch fails it can cause the starter or reverse lights not to operate. Other complications can occur if a loose connection exists near the wiring connector, confirm this connection by remo...

Engine Working Of Car Engine Helpful Information Engine's are designed to have any number of cylinders and are created in all sizes. The pistons are designed to fire consecutively to rotate the crankshaft inside the engine block. Motor oil is used to cool and lubricate internal engine parts including the crankshaft, camshaft, cylinders, pistons, piston rings, wrist pin, lifters, rock arm, followers, intake and exhaust valves, timing gears and chain. The oil then travels back into the oil pan creating a recirculation system. The oil pump determines the amount of oil pressure the engine will have via a pressure spring fitted into a relief valve of the pump. There are primarily two styles of valve train systems, "overhead cam" which consists of a camshaft mounted on top of the cylinder head, and  "in block" systems which consist of a camshaft mounted inside the engine block, designs to perform this action will vary depending manufacturer. The cylind...

Emissions Working Of Emission Control System In Car Helpful Information Emission control systems have been incorporated into automobiles to prevent pollution by limiting the amount of partially burned and evaporated gases into the atmosphere. These systems have been efficient in reducing the air pollution caused by automobiles to a large extent. Increased engine efficiency and lighter vehicle construction has also contributed to helping reduce emissions. The different aspects of emissions are tailpipe emissions, life cycle emissions and evaporative fuel emissions. Unspent fuel vapors are known as the main contributors to air pollution. These omitted gases consist of carbon monoxide, hydrocarbons, carbon dioxide and nitrogen oxide. Lifecycle emissions are byproducts which are released into the environment during the manufacturing, maintenance and disposal of the vehicle. These products include volatile solvents such as auto paint and lubricants, manufacturing plant waste...
