Generator charging circuit has poor contact, or the generator terminal bolts are loose. This is caused by insufficient power generation from the alternator. Below are relevant details: 1. Battery: A car battery is a type of storage battery, also known as a lead-acid battery, which works by converting chemical energy into electrical energy. Typically, the term refers to lead-acid batteries that use lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. 2. Notes: Like all batteries, a car's 12-volt battery will eventually drain if not recharged, which is why vehicles have built-in charging systems. Most cars are equipped with an alternator and voltage regulator to recharge the battery and power the electrical systems while the engine is running.

What is the difference between 1.5T and 1.5L engines in cars?

The difference between 1.5T and 1.5L engines in cars lies in their engine types: a 1.5T engine is a turbocharged engine, while a 1.5L engine is a naturally aspirated engine. Turbocharging is a technology that uses exhaust gases produced by internal combustion engines to drive an air compressor composed of two coaxial impellers. Naturally aspirated engines work by drawing air into the combustion chamber solely through atmospheric pressure, without any form of forced induction. The engine is the power-generating device of a car, acting as its heart, and determines the vehicle's power, fuel efficiency, stability, and environmental friendliness. Based on their power sources, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid engines.
