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.
Audi Makes New Engine 1.8-liter 170 hp
Audi has unveiled a new engine with a capacity of only 1.8 liter TFSI technology. However, do not run in conventional machines, yes, because this machine is also much faster fuel.
Set of four-cylinder TFSI new states, which is 170 hp and 236 Nm of torque the engine mated to a manual gearbox, the Audi A5 Coupé accelerates faster 0-100 kph in just 7.9 seconds and top speed reaches 230 km / hour.
Apparently, Audi, “The character of the combustion engine will focus on the development of this machine.” The secret, apart from the turbocharger, this engine provides two injection systems directly and indirectly. The second injection system operates at the end of the intake manifold near the intake valve.
To further optimize the mixture of gas and fuel-system control valve has been given more leeway. Audi valve lift system, the strength of the valve on two stages, active fit into the exhaust.
Hope, with a working system, the latest 1.8-liter TFSI engine can still power the car but keeps its energy efficiency.
