Types of Car Engine

Types of Car Engine

1. VTEC (Variable Valve Timing and Lift Electronic Control) 

VTEC stands for Variable Valve Timing and Lift Electronic Control, is a regulator valve technology invented by Honda, and is still used by a range of engines that have not embraced Honda i-VTEC. VTEC technology advantage lies in the ability of the small cylinder engine produces power comparable with large cylinder engine, and in addition, it also gives good fuel consumption, and also can be used on a daily basis. 

1. Small engine cylinder, capable of producing power comparable to large-cylinder engine. 

2. Give good fuel consumption. 

3.Keeping to optimum engine performance, good for low rpm and high torque. 

4.Process exhaust variable valve does not require opening more smoothly because the exhaust gas, so the engine will work more lightly. 

Because the use of oil, VTEC work could be disrupted due to lack of engine oil, dirty or low oil pressure due to a leak in the system, such as O-rings are damaged

2. i-DSI (intelligent Dual and Sequential Ignition)

I-DSI engine as the smart technology that is designed specifically for a compact car, with 2 spark plugs in each cylinder in the combustion chamber and the combustion time intelligent control, can achieve ultra-high fuel economy with low fuel consumption and economical, as well as generate maximum torque at low to medium RPM rotation, according to the speed of everyday use. 

I-DSI engine burn more efficiently, resulting in a more responsive power cars, most fuel-efficient in its class, and exhaust emissions cleaner.

3.SOHC and DOHC

Between SOHC with DOHC does have a big difference in concept. Both terms are talking about the movement of the valve mechanism. SOHC stands for Single overhead camshaft, while the DOHC stands for Double overhead camshaft. Seen from the abbreviation of the two there is the same word that is, the camshaft or camshaft as. Indeed, it is located on the camshaft as the difference between the two technologies.

The desire to create a more powerful engine than the model SOHC, DOHC technology led to the birth. DOHC engine has a more refined sound and engine performance that is better than the SOHC because each shaft DOHC engine has a different function to regulate entry and exhaust valve. Meanwhile, the SOHC engine, one shaft at the same time responsible for managing the open / close valve incoming / exhaust so that the combustion occurs in the engine more leverage and acceleration DOHC DOHC engine cars for the better. 

DOHC camshaft wear two axles are placed on the cylinder head. One to move the suction valve and one exhaust valve to run. This system does not require the opening and closing of the rocker arm so that the process becomes more precise work again at high speed.

4. VVT-i (Variable Valve Timing with intelligence)

Engine that was first introduced in 1996 has been used in most cars Toyota Not only that machine is claimed to make the engine more efficient and powerful, environmentally friendly and fuel-efficient. then how the system works to be able to create satisfactory results. Easily VVT-i system will continue to correct the valve timing or line out of the fuel and air. Adjusted by stepping on the gas pedal and the burden to produce optimum torque in each round and the engine load. By doing so will result in optimal power, fuel-efficient and environmentally friendly.

Excellence VVT-i 

1. Every optimal power engine rpm, the valve system to support the combustion process is more effective in generating maximum power. 

Fuel 2.savingt, electronic valve setting makes the fuel consumption to be frugal and efficient. 

Discard 3.Gas Environmentally Friendly, supply of fuel and air are regulated by the valve action makes the combustion system to be perfect, and the resulting exhaust gases into clean. 

4.Noted more than one variant of Toyota's VVT-i technology adopts this like the Toyota Avanza, Toyota Innova, Toyota Yaris and Toyota Vios sedan.
