Audi is the brand of the world's early adopters of the FSI direct injection engine. Audi FSI engine in the domestic release of only the homogeneous combustion mode, yet stratified combustion. The main reason is that the stratified combustion using lean mixture, the cylinder temperature also increased the harmful emissions of nitrogen oxides, and will undoubtedly improve the purification requirements and cost. In addition, the stage of the domestic fuel oil sulfur content of gasoline catalytic converter damage.
Audi to introduce domestic FSI engine with homogeneous combustion technology. Equipped with a V6 3.2 FSI engine the Audi A6L, accelerates from zero to 100 km / h in just 7.7 seconds, its top speed of 240 km / h; 90 km / h constant speed fuel consumption of 7.4 liters / 100 km. Equipped with a new valve control technology can also be ordered to make efficiency savings of 5% of the fuel. In fact, has a childhood displacement in displacement of the FSI engine family has become the main engine of the Volkswagen (Audi).
Also extends from the FSI with the TFSI (turbocharged fuel stratified injection engines) regardless of the pressurization system, which is the increase in the FSI engine on the basis of a turbocharger. The turbo is a high temperature and pressure to promote the use of exhaust waste gas turbine high-speed rotation, into the gas turbine driven by compressed air intake, air density, and increase the amount of fuel injection and computer control, with the intake of high-density, so the displacement under the same conditions to improve engine efficiency.
In fact, not just General Motors and Volkswagen, some well-known brands, including Porsche, Ferrari, are beginning to put into the development of direct injection engine, although they progress vary, but one thing is certain, that is, with the direct injection technology trends perfect, its lower production costs, direct injection technology is becoming mainstream, which would explain why the mass introduction of more and more FSI engine to the domestic, while GM has introduced a smaller displacement of the SIDI engine, a generic , Volkswagen and other play a major role, more and more brands to participate in the DI era of direct-injection engine is overwhelming toward us.
The new factory suspected of illegal land were forced to a standstill, postpone the return of A shares, the Hong Kong stock shares almost cut, fund holdings, Morgan Stanley lowered sales expectations and investment rating. BYD Company (01211.HK) trouble.
At the same time, BYD still, as always, a high profile in the solar power generation and electric vehicles. Perhaps Wang, all the troubles, such as technical problems are generally habitually overcome. Compared with the above-mentioned iron batteries, BYD car dvd player and auto dvd has been boasted that "nuclear weapons" will be put into mass production, perhaps it will feel really happy.
Outside the much-anticipated years of BYD's "core technology", as well as BYD committed to enter the solar energy and other new energy layout is BYD focus on the secret front of the troops. However, the mysterious indeed mysterious, but also in the outside world can lead to doubts. Has always been known as low-cost advantage, technical research capabilities, whether it is able, as in the field of rechargeable batteries in the field of new energy Cuikulaxiu continue to occupy leading and would like it known as "the world's first production dual-mode electric vehicle and the F3DM general, I saw the stairs but no one is down
