Dual Valve Technology the Smart Valve Increasingly Complex
Moment-double-valve technology (multi-valve), variable valve timing and valve timing (VVT) on the combustion engine is constantly changing.
Increasingly complicated
Toyota VVTi (Variable Valve Timing intelligent), the last Honda i-VTEC (Variable Valve Timing and Lift Electronic Control with intelligence), Suzuki VVT (variable), while Mitsubishi MIVEC (Mitsubishi innovative valve timing control valve of the electronic system) and VANOS (variable Camshaft Timing) BMW.
Toyota also has a ‘dual VVTi “played the system as a new machine which was introduced last year. In essence, as the area as Noken optimum spark advance degrees or rewind, or could allow also known that the opening of the intake valve on the fuel supply of the rapids.
In VVTi, the operating principle of this technology is the way Noken the right to move the camshaft forward and backward. Noken result was used to determine the degree of opening and closing the valve adjusts the speed to be determined.
If the engine speed is low grade, of course, there is no need to open and close the valve top. As fuel in the combustion chamber as needed only a few machines.
However, if the engine speed is higher VVTi sent the degree of opening and closing Noken no longer correspond to the fuel tank of the machine. As the solenoid valve works on controlled by oil pressure.
In the dual VVT-i engine, fuel and electricity are produced larger and more uniform. This is because the process of opening and closing the intake valve is not only, but also in the exhaust.
The goal of high-speed (acceleration of the exhaust valve opening), the fresh air and fuel are much faster (does not inhibit the exhaust).
All low-speed, time to close the valve quickly adjusts itself to the ‘drop’ a mixture of fuel and air for the new entry to be reduced. This is important to retain power, fuel consumption and emissions.
Development of Machine Technology save Money the Main Goals
Crawl 90, development to the engine fuel injection system began, ignition system has become more demanding and has grown until today. But compared to gasoline, diesel follow drinkers’ kitchen has rapidly developed over the past 20 years.
Indirect combustion system in a direct-injection technology used to make diesel engines for use in any application of energy enhancer rivals, and of course a question of fuel efficiency.
For gasoline engines, the events of this kind are quite surprising.
Multi-point injection
This technology makes the engine more efficient by an injector for each cylinder. Gasoline direct injection sprays of steam into the combustion chamber. In fact, education is the perfect mixture in each cylinder and provides less fuel, fuel consumption and fuel efficient.
Multivalve
In the late 80 and applied in several systems with more than two valves per cylinder. But the development in most of the prolonged by the use of four valves per cylinder. In fact, the supply of fuel or fumes, and more can be routed to the optimum.
In addition, variable valve timing, that is set when opening / closing the valve with the Wankel engine. The names for these systems, like BMW VANOS, VVT-i, then the VTEC. Of course, even if in principle the same as the individual differ from each other.
VGT (variable geometry turbocharger)
Used turbochargers for diesel engines have been to use the exhaust gases to improve engine performance. Now, with the development of this turbine, the system of variable geometry turbocharger allows the reduction of turbo lag.
VGT, with fins was at home that all the appropriate opening engine screws properly. Indeed, the attraction, which always take place optimally in each round.
Ferrari 458 Italia Machines
Functioning like a heart is the main driver of the car. And as an exclusive and expensive sports car is the Ferrari 458 engine on Italian handmade (hand) are developed carefully and completely.
This machine is in itself a capacity of 4.5-liter V8 capable of spraying up to 562 hp. The result, 458 capable of 0-100 km in 3.4 seconds in Italy.
The assembly of the machine in the production of Ferrari in Maranello is made is not only the Italians Italy manufacturers to build 458 engines, but also builds the engine and Maserati Ferrari California.
Manufacture of precision machines relies on the hand of man. To make visible, from the crankshaft and the block-making, with three thickness categories and will be the best.
In addition, the process takes about oil drilling and the hole with modern amenities yet in hand, without the robot. Install the piston is manually and will continue to do with the layer thickness.
Then there is the step of mounting the crankshaft, which is almost intact nerve car. And the phase of implementation, after the engine is responsible for bearing oil cooler and water. Final phase of the trial, immediately after the engine mounted in the engine compartment 458 Italians.
