Who can tell me some knowledge about car engines?

1. The W-type engine is an exclusive engine technology of Volkswagen in Germany. Compared with the V-shaped engine, it has a lower height, a shorter crankshaft and a lighter weight. But its complexity is also imaginable, and due to the increase in width, the engine will fill the space, so it is destined to be installed on a luxury car.

2. Some dry knowledge about automobile generators and batteries. Cars rely on engines to drive generators to generate electricity. Car engines are not only used to drive vehicles, but also power many systems in the car. The engine crankshaft has two ends, one end of which is connected to the flywheel, which needs to be docked with the gearbox to drive the vehicle.

3. The role of the car engine. The car engine is a device that provides power for the car. It is the heart of the car and an energy conversion device. Its function is to convert the thermal energy of gasoline (diesel) into mechanical energy by burning and expanding the gas in the sealed cylinder, pushing the piston to work.

4. The up and down movement of the piston is divided into four strokes: intake, compression, work and exhaust. The engine with these four strokes is called a four-stroke engine. Piston: The piston has to withstand the high pressure and high temperature caused by the combustion of the mixed gas in the cylinder, so there are special requirements for the strength of the piston.

5NR one FE engine durable?

Comparise in the engines used in the same type of carA more durable type of engine overview Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Sterling engines, steam engines, etc.), electric motors, etc.

Detailed explanation of Vechi engine Model: 5NR-FE Origin: partially domestic/imported Year of installation: 2019 Performance parameters: maximum power 81KW (6000rpm), maximum torque 138Nm (4000).

Good. Powerful power: The 5NR-FE engine adopts the VVT-iW intelligent wide-angle variable valve timing system, which improves combustion efficiency and achieves more accurate valve control. By optimizing the intake and exhaust processes, the engine can generate greater torque and power output, providing strong driving force.

No. According to public information, the 5nrfe engine will not burn oil after running 300,000 kilometers, and it rarely burns oil. The Toyota 5nrfe engine is an engine widely used by Toyota in small and medium-sized vehicles. The electronically controlled engine is a comprehensive engine controlled by a microcomputer.

Model specifications: 5NR-FE Origin: part of domestic/_port Year of use: 2019 Technical parameters: up to high power 81KW (6000rpm), maximum torque speed 138Nm (4000).

Power durability: Toyota Wich is equipped with a 5NR-FE engine, with a maximum power of 81kW and a maximum torque of 138N·m, and the transmission is a 5-speed manual transmission.

What are the types of engines

Gasoline engine Gasoline Engine (Gasoline Engine) uses gasoline as fuel The engine of the material. Due to the small viscosity and rapid evaporation of gasoline, gasoline can be sprayed into the cylinder with a gasoline injection system. After compression to a certain temperature and pressure, it is ignited with a spark plug to expand the gas.

According to the fuel used, there are: gasoline engines (referred to as gasoline engines), diesel engines (compressed combustion engines) and special fuel engines (such as natural gas, hydrogen and alcohol engines). Gasoline engines are relatively small in size, light in weight and low in noise, while diesel engines are relatively large in size, powerful, economical and relatively noisy.

In-line engines are widely used in domestic cars. Almost all domestic cars below the mid-range and models with four-cylinder engines are in-line engines.

There are several types of classifications of automobile engines: according to the type of power, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid power, etc. According to the classification of the air intake system, it can be divided into four types: natural intake, turbocharging, mechanical supercharging and double supercharging.

Everything about the engine

It is generally believed that the V-shaped engine is a relatively advanced engine, so it has become one of the symbols of the sedan class. The structure of the V8 engine is very complex and the manufacturing cost is very high, so it is rarely used. The V12 engine is too large and heavy, and only a few luxury cars are used, such as the BMW 760Li mentioned above.

First of all, the engine parts of the car have pistons, valves, camshafts, crankshafts, cylinder pads, gasoline pumps, fans, thermosters, generators, starters, ignition coils, etc. Different parts have different functions for automobile engines, and each part is crucial for automobile engines.

Hello, dear! LaunchEngine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (resurrected engines), external combustion engines (Stling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy.

Start-up, the start-up device is the most critical. If there is only the engine and no start-up, the engine is equivalent to a decoration. This system is like the key to open the engine. Engine management, which is equivalent to the human brain, controls everything the engine.

Engine cylinder deficiency mainly means that one or more cylinders of the engine are not working properly. It is manifested as: the exhaust gas flow discharged by the car has obvious intervals, and the exhaust pipe shakes heavily, which can be clearly felt the shaking of the engine, sometimes accompanied by a sudden sound.This is mostly related to the failure of the ignition coil.

Where is the car engine?

1. The installation position of the automobile engine - the central central engine, that is, the engine is located between the front and rear axles of the vehicle, and the cockpit is generally located in the front or rear of the engine. It can be said that the car with the middle engine must be rear-wheel drive or four-wheel drive.

2. The front engine of the car is generally divided into front-wheel drive and front-wheel drive, and the engine is generally in the front of the car. The engines of domestic vans are generally under the front seats, while high-performance sports cars use middle or rear engines. The engines of buses and buses are at the rear.

3. The car engine is a device that provides power for the car. It is the heart of the car, which determines the dymility, economy, stability and environmental protection of the car.Some are at the head of the vehicle, some are in the middle of the vehicle, and some are at the rear of the vehicle. The engine is at the front of the vehicle.

4. The engine of Chang'an Ouno is in the engine compartment of the vehicle, that is, under the front hood of the vehicle. Pull the switch and open the hood to see the engine. The specific operation steps are as follows: open the door on this side of the cab. Pull the hood switch on the left side of the driver's leg.

Introduction of automobile engine includes several parts of engine structure

1. Crank connecting rod mechanism Crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a fusele group, a piston connecting rod group and a crankshaft flywheel group.

2. Engine: structural composition A.Crank connecting rod mechanism: connecting rod, crankshaft, shaft tile, flywheel, piston, piston ring, piston pin, crankshaft oil seal; to realize the working cycle and complete energy conversion is the key moving part of the engine.

3. Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis constitute the frame of the tractor.

4. The engine structure of the automobile engine is composed of several parts, namely intake manifold, intake valve, piston, crankshaft, generator, tension pulley pulley, crankshaft pulley, timing chain, throttle valve, spark plug, oil span shell, connecting rod, exhaust camshaft sprocket, exhaust camshaft, exhaust manifold and Air intake camshaft.
