Set the Valve without Camshaft
Multi-Air engine Fiat is a new discovery by the automobile manufacturer Fiat made to produce the energy efficiency of the engine, but the couple is still powerful and great. Basic concept is the creation of the combustion in the engine that meets your needs. It is not exaggerated and scarcity, the combustion takes place “in shape”, according to the required power and torque.
To create an adequate supply of combustion engine development was difficult, the fuel mixture into the combustion chamber to create an effective mechanism with variable valve timing. The variable valve control system with multiple-choice and duration of valve opening and valve lift (which is controlled by the camshaft) engine speed to work if necessary. The same applies to several air-Fiat engines.
Difference if the variable valve timing is limited to a period of several options and opening lift valves (usually two), and still dominated by the camshaft, while time-multi-Fiat engine and air valve is opened, while a very flexible electronic devices.
Not only to meet over a period of two scenarios valve opening to the needs of the machine, but especially to the needs of power and torque.
Camshaft in the valve not to get away instead of electronic devices for the input of the camshaft in the valve. This electronic device reads a variety of sensors in cars and engines up to speed, the conditions for the rotation of the motor temperature and the response and the willingness of the driver, the electronic device that the opening of the valve, the needs of the combustion modified with a solenoid valve.
For example, if the need for maximum performance at the opening of the suction valve opens fully consistent as a mechanical camshaft, which maximize specifically for the performance at high speeds.
As for situations that require low-end torque, the valve will close in the order early. Conversely, including the flow of the mixture of fuel and air and maximizes the air mass in the cylinder. There’s even a scene from the opening of valves called multi-level, where to open in one step into the suction valve twice as fast and not too high, you can.
The aim is to improve the turbulence in the combustion chamber, which is useful when the machine is operating in a low engine speed increase, when running in stop and go traffic. What are the benefits and the mechanism to open the air valve of the engine several Fiat? Fiat says about a mechanism that can be used by 10 percent for gasoline and diesel, the torque at low speeds by 15 percent was claimed to be better.
This machine also has a volumetric efficiency of the engine 25 percent more compared to a conventional engine with the same power. This was finally able to remove the emissions from 40 percent to burn hydrocarbons and carbon monoxide (HC / CO) and 60 percent of nitrogen oxides.
