What is the difference in angle between the crankshafts of a six cylinder engine? Does anyone know?

At present, most of the engines are four-stroke engines, and the piston is from top dead center to bottom dead centerCrankshaftRotate 180°, then complete a engine working crankshaft needs to rotate 720°, in order to make the engine work smoothly, 720° is divided equally to 6 cylinders, so the angle difference between the crankshaft crankshaft crankshaft is 120°.

V6 engine.

It is a compact engine build, which is shorter than an in-line four-cylinder engine and is more compact than the V8 in most designs. Because of this characteristic, the V6 engine is widely used in cars with a front-wheel drive layout. Because of Hyundai.

The engine is being left to be smaller in size but requiring more horsepower, so more compact V6 engines are becoming more common.

The fuel stratification injection V6 engine (TFSI) and Ford's turbocharged and direct fuel injection Ecoboost engines are both compatible with Volkswagen's liter-liter naturally aspirated V8 engine.

Comparable. Most of today's V6 engines are available in displacements up to 4 litres, but there are some larger or smaller V6 engines.

The angles of 1 and and 4 are the same, which is equivalent to being divided into thirds, with a difference of 120°, and the working order is 153624 This is exactly two weeks of rotation.

The angle between the crankshafts of a six-cylinder engine is 360 divided by 6, which means that the crank angle is 60 degrees.

The number of crank of ordinary engine = the number of cylinders, and the number of crank of V-type engine is half of the number of cylindersStrictly speaking, it should be a variant of the V-type engine, the number of cranks is half of the number of cylinders, and the crankshaft is basically a staggered structure.

The crankshaft is the most important component in an engine. It takes the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is subjected to the centrifugal force of the rotating mass, the gas inertia force of periodic change and the reciprocating inertia force, so that the crank bearing is subjected to the action of bending torsional load.

Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, uniform and balanced.

A connecting rod journal (crank pin), two crank arms on the left and right and two main journals on the left and right constitute a crank, and the crankshaft is composed of a plurality of cranks. The number of crankshafts of in-line engines and horizontal engines is equal to the number of cylinders. The number of cranks of the V-type engine is half of the number of cylinders, and there will be two crank pins that are dislocated from each other on a crankshaft of the staggered crankshaft, and the W-type should be a variant of the V-type engine strictly speaking, the number of cranks is half of the number of cylinders, and the crankshaft is basically a staggered crank structure.

The relationship between the crankshaft diameter and the main journal - the main journal has one more than the crankshaft warp.

Number of crank = number of cylinders. However, the arrangement of the cylinders is different.

No matter how they are arranged, there are two cranks per cylinder.

The angle between the crankshafts of the four-stroke six-cylinder engine is 120 degrees.

Power stroke: The process of converting the internal energy of fuel into mechanical energy inside the engine. Whether it is a two-stroke engine or a four-stroke engine, it must go through four working processes: intake (sweeping and combustion) gas, compression, combustion expansion, and exhaust in order to complete the working cycle of one god and friend.

Work principle: In a four-stroke engine, the piston moves twice for every two rotations of the crankshaft (720 degrees), and the engine completes a working cycle of Youhuai, that is, each stroke completes a working cycle. In a two-stroke engine, the piston moves back and forth once every revolution (360 degrees) of the crankshaft, and the engine completes a working cycle, i.e., one work cycle every two strokes.

Fourth, the angle between the pure and clear crankshafts of the crankshaft of the crankshaft of the four resistant strokes is ().

Correct answer: 120°

A four-cylinder engine, also known as a four-cylinder engine, is a machine that can transform one form of energy into another, more useful one. It is usually the conversion of chemical energy into mechanical energy. Sometimes an engine is applied to both a power generator or an entire machine including a power unit, such as a gasoline engine or an aero engine.

The main part of the motor is the cylinder, which is the power source of the whole car. The body of a four-cylinder engine is mainly composed of components such as a cylinder block, crankcase, cylinder head and head gasket. The basic principle of a four-cylinder engine is to convert the thermal energy of gasoline (diesel) into mechanical energy by pushing the piston to work when the combustion gas expands in the sealed cylinder.

Main uses: mostly used in car engines, motorcycles, chain saws and other low-power power machinery.

Combined with the new frame, swingarm and head and tail suspension system, the all-new R1 can be more precisely shaped and more accurately distributed. In addition to the more accurate control of torque, the exhaust sound is also more attractive and more attractive. Compared to the current R1, the crank diameter of the R1 in '09 was increased from 32mm to 36mm to meet the needs of the crankshaft.

The engine compression ratio of the all-new YZF-R1 is 1, and the bore stroke is mm x mm (the previous model was 77mm X, and the bore ratio is as high as the supercar, which is a supercar setting of the super over-square). The new R1 has a peak horsepower (naturally aspirated, not counting RAM-Air mode) at 182ps at 12,500rpm and a torque of 12,500rpm.

Compared to the '07 R1, there is a slight increase of 2PS horsepower and torque. Yamaha was the first car manufacturer to be brave enough to put a cross-type crankshaft on a market-selling sports car. Commercially available sports cars don't run once and have a dedicated team to overhaul them, so the first performance is to be stable, which requires quite accurate calculations and matching.

This is convenient to see that Yamaha's strength has gone to that level. So on the whole, 99% of the cars on the market are not made into cross crankshafts, and the most important reason is cost.

Referring to the example of a Yamaha motorcycle cross crankshaft, wouldn't it be smoother to use a 90-degree crankshaft? Is it the technology that is not up to scratch or is there something else?

99% of the cars on the market are not made into cross crankshafts, and the most important reason is cost.

You are a few cylinders of the engine, the 4-cylinder engine is generally 1342 (clockwise order when the crankshaft is driving, from the left side of the number 1 cylinder) 6 cylinders are generally: 153624 In addition, when the crankshaft is arranged, it is necessary to pay attention to the stress distribution of the crankshaft and choose the appropriate material, because when the engine is running, the crankshaft part produces alternating stress, and the requirements for the crankshaft are relatively high.

Such a setup is conducive to bringing out the best in the engine.

The main thing is to be able to run better when the car is started.

The cost of manufacturing and maintenance is higher, and the cross crankshaft is not easy to make.

Most of them are limited by technology and cost.

Because this can be more convenient, more cost-effective, and easier to repair.

In order to better produce and use automobiles.

Because the curved surface arrangement is easier to repair than the cross crankshaft type.

The technical requirements are not met, but the technical requirements for this are still very large.
