Parts of internal combustion engines (Petrol, Diesel, Gasoline, Electric) | TECHNOLOGY FACTS

What are the components of a petrol vehicle. Engine: The engine is where fuel combustion takes place. In a petrol vehicle, it's typically a four-stroke internal combustion engine. It has cylinders where pistons move up and down. The intake stroke draws in a mixture of air and petrol, the compression stroke compresses this mixture, the power stroke ignites it with a spark from the spark plugs, and the exhaust stroke expels the resulting exhaust gases. Fuel System: The fuel system starts with the fuel tank where petrol is stored. The fuel pump draws petrol from the tank and sends it to the engine through fuel lines. In modern vehicles, fuel injectors spray the petrol directly into the engine's cylinders. In older vehicles, a carburetor mixes air and fuel before sending it to the engine. Exhaust System: After the fuel is burnt in the engine, the exhaust system manages the resulting gases. The exhaust manifold collects these gases from the cylinders. The gases then pass through the...

Manual Car Transmission System. Manual car transmission, also known as a manual gearbox or stick shift, is a type of transmission system that allows the driver to manually select and change gears in the vehicle. It is commonly found in older cars and some sports cars but has been gradually replaced by automatic transmission in many modern vehicles. 1. Components : These components work together to enable gear selection, transfer power from the engine to the wheels, and controls the movement of the vehicle. Gear Shift Lever : The gear shift lever, also known as the gear stick or shifter, is the control interface used by the driver to manually select different gears. It is typically located in the center console between the front seats, and its position and movement determine the gear the transmission is in. Clutch Pedal : The clutch pedal is located to the left of the brake pedal (in left-hand drive vehicles) and is used by driver to engage o...

Classification of pumps and their working principles | TECHNOLOGY FACTS

positive displacement pumps Positive displacement pumps are a type of pump that operates by using mechanical action to displace fluid from an inlet to an outlet. These pumps are designed to move a fixed amount of fluid per cycle or revolution and are known for their ability to generate high pressures, handle viscous liquids, and maintain a consistent flow rate. They are widely used in various industries, including oil and gas, chemical processing, food and beverage, pharmaceuticals, and water treatment. Here are some key characteristics and types of positive displacement pumps: Principle of Operation: Positive displacement pumps work by trapping fluid in a cavity and then forcing it out to create flow. The cavity expands and contracts as the pump's mechanism moves, thereby generating the desired fluid displacement. Fixed Displacement: These pumps move a fixed volume of fluid per cycle, regardless of the system pressure. This characteristic makes them suitable for applications requi...

What is the difference between an electric motor and an internal combustion engine?

The comparison between fuel engines (internal combustion engines, ICE) and electric motors revolves around several key factors, such as efficiency, performance, environmental impact, cost, and technology. Below is an overview of these differences: 1. Energy Source Fuel Engine : Uses fossil fuels (such as gasoline, diesel, or natural gas) to generate power. Fuel is burned in an internal combustion process to produce mechanical energy. Electric Motor : Runs on electricity, usually sourced from batteries or electric grids. The electricity can come from various sources, including fossil fuels, renewable energy (solar, wind), or nuclear. 2. Efficiency Fuel Engine : Typically has an efficiency of 20-30%. A large portion of the energy from burning fuel is lost as heat, making it less efficient. Electric Motor : Much more efficient, typically around 85-90% in converting electrical energy into mechanical power. Most of the energy in an electric motor is directly used for propulsion. 3.
