The combustion engine in our cars would not function without fuel. Supplying this essential fuel into the combustion chambers are the fuel injection systems. Many attributes of your car are highly influenced by the type of fuel injection system its engine has, mileage, ride quality, engine life, etc. A fuel injection system is a mechatronic circuit that is the combination of mechanical and electronic circuits to supply fuel of ideal volume into the engine. Anil Since the fuel injection system is such a vital component, engineers around the globe have evolved it to its most efficient and effective version. In this day and age, while there are various types of fuel injection systems available, the broad categorization brings them down to four main types: Single point fuel injection, Multi-point fuel injection, Sequential fuel injection, and Direct fuel injection. Let’s go through these categories one by one and understand their functionality. Anil Single-Point Fuel injection or Throttle-...

ABS Braking Facts Q.What is the function of EBD with ABS? In the Anti-Lock Braking system, when the brakes are applied, an electronic control unit doesn’t let the wheels lock and keep them intermittently rotating. During rotation, due to road conditions, different speeds, and loads, all four wheels need a different amount of brakeforce to bring them to rest. The Electronic brakeforce distribution detects the brake force required by each wheel and supplies just as much as needed to keep the vehicle balanced. Q.What are the mandatory safety features in cars in India? The mandatory safety features in cars in India are ABS with EBD, rear parking sensors, dual front airbags, rear parking sensors, hill hold control, seatbelt pre-tensioners, and speed sensing door locks. Q.On what kind of surfaces ABS doesn’t work? ABS can be ineffective on gravel surfaces, icy conditions, or very wet surfaces. This happens because when the ABS partially releases the barkes from the wheels to let them co...

What Is the Construction Structure of an Air Brake System? Air brake systems have a two-stage air compressor with gearbox shafts or a crankshaft. Here is what happens inside the unit: This system intakes air from the atmosphere, compresses it and delivers it to the storage tank through a valve.  When reservoir pressure attains maximum degree, the unloader valve opens. Then, the compressed air is directly released into the atmosphere. All four wheels with brake chambers have a diaphragm, which forces air pressure. This force operates the camshaft that runs the lever and applies brakes. Each brake chamber connects to a brake pedal, and an air filter fits between the brake valve and storage tank. Below is a step-by-step procedure for the functioning of air brakes: How do Air Brake Works ? Step 1: When a driver starts a car's engine, the brake compressor activates as it functions by the engine. Then, the brake compressor starts compressing the atmospheric air.  Step 2: Through the...

Principle of Air Brake System If finding how do the air brakes work, it is explained in simple words below: Compressed air inside the air brakes activates the brake system.  This system consists of an air compressor, air filter, unloading valve, air reservoir, brake valve, and brake chamber. These compressors allow atmospheric air to flow through air filters and compress it. This airflow is reserved in storage tanks or reservoirs.  Air from this reservoir flows to several sections of the automobile that functions on compressed air. A section of compressed air flows into the brake valve, which a driver controls. A driver handles the braking intensities of a vehicle in emergencies. Pedal Released : As a driver releases brake pedals, the master cylinder in this system shifts to its original position. It happens due to the piston spring, which results in the dropping of air pressure. This function allows releasing of brake shoes from a brake drum releasing brakes. Pedal Depressed ...

Advantage of Air Brake System   There are several advantages of an air braking system. Here they are as follows: The air brake system is an effective mechanism than the other braking mechanisms. It allows easy designing of chassis as the components of air brakes sit conveniently. It requires only air as a primary medium which is available in abundance. Air brake system ensures safety when applying brakes suitable for trucks and heavy vehicles. This system ensures better control and reduces stopping distance. The air brake system comes with a flexible hose connection and easily stores air at high pressures. This system is not prone to leakage as air is the major component. It is not the case with hydraulic brakes that use fluid to function. Air brake allows less wear and tear on components. Air fluid stores potential energy as it is compressed. So, it can control the force applied. Compressed air can be used for horns, tyre inflation wipers, and other accessories. Air line couplings...
