In most cases, there are three primary reasons for a tangible loss in the acceleration dynamics.
- The pressing of the accelerator pedal causes decreases in power: in such cases, the car’s engine requires more fuel than the fuel supply system currently supplies it.
- Due to a buggy electronic control unit.
- Because of a failed spark plug, a coil, damaged high-voltage wire, malfunction of the fuel system.
To find out the actual reason behind the dips in the usual operation of the engine, you need to contact a reliable car service centre in Delhi and perform several checks and replacements.
Causes of failures when pressing the gas pedal
The accelerator is a control by which the driver controls the volume of the combustible mixture. After which, the fuel enters the engine cylinder so that the car goes faster or slower. However, various systems are responsible for the air-fuel ratio (mixture quality) that the driver does not control, but by the brain of the car (ECU), or mechanics (carburetor).
In a carburetor, this dosing is much easier – the cross-section of the primary jet hole through which the fuel passes becomes larger or smaller. Moreover, the main work of the engine is to ignite the mixture with a high-quality spark, and the required effort to turn the crankshaft will become accessible.
In a modern fuel injector system, a change in the position of the gas pedal gives a command. Before executing such commands, the electronics control unit performs a thorough check using pressure and temperature sensors. In addition, it also displays the speed of the crankshaft and camshaft, the consumed air volume, and the content of residual oxygen in the exhaust gases.
Throttle failure occurs due to:
- Single or multiple sensors display incorrect data, missing or out of the baseline.
- Electronics components have accumulated a whole slew of critical errors (in such cases, you need to overwrite the dump and flash memory).
- Something stops the fuel from entering the cylinders at full capacity.
- Something makes it challenging for air to enter into the cylinder in an adequate amount.
- Some things make it hard to evacuate the spent mixture into the exhaust manifold.
- Spark gaps form in one or more cylinders.
- The spark plug becomes unable to ignite the fuel at the right moment.
If the car is “old”, it will need doorstep car cleaning in Delhi and comprehensive diagnosis because all of these reasons can cause the problem simultaneously.
Such problems can also occur when injectors, intake, and exhaust manifolds are worn out and clogged, Hall sensors and BB wires also fail in old age, compression decreases because of wear, hydraulic and spring compensators in the cylinder head become tires, and advanced settings float. In cars with low mileage (up to 100 t. km), usually, single units fail. When it comes to the second MOT – most often, a factory defect becomes visible or a consequence of poor-quality assembly.
