I will be shared, auspicious getting the main reason that 3 crocks of machine popularize on the gram to have 3:
1. gets gram and Woerwo to share truckload the result with dynamical assembly platform
(1) the dynamical assembly platform that says Woerwo simply first
Wo Erwo is current the core of product strategy is truckload change with dynamical assembly platform. Truckload it is CMA platform, dynamical assembly is Drive-E platform (graph 2 graphs 3 graphs 4) . The core of Drive-E platform is: Engine miniaturization + modular + electrification. Wo Erwo is the company that offerred assembly of whole motive force clearly earlier to change electrification to the strategy, cut engine breed as far as possible, rely on electrification to satisfy different requirement. The platoon amount that Drive-E determines Wo Erwo engine is the biggest is 4 crocks of 2.0L, make the engine of bigger quantity no longer. 0.5L of one-cylinder of Drive-E series engine adjusts an amount through adjusting cylinder amount. Produced 2.0T4 crock and 1.5T 3 crock so two modular engine products, the supercharger that differs through matching next and confuse the property that uses systematic implementation to differ, satisfy the requirement of product of Wo Erwo whole set.
(2) auspicious get gram and Woerwo in all platform
Auspicious the biggest profit going up from the technology after buying Woerwo is to be able to share the CMA that develops together with Woerwo truckload technology of platform of platform technology and Drive-E motivation assembly. The attention is to share a technology, either in all line production, also not be to be purchased directly, however both use same platform technology, but the model that develops oneself severally, respective investment builds a plant, produce with respective vendor system a future life go to. Undeniable is auspicious the core supplier resource that also used a lot of Wo Erwo dominant positions.
Accordingly, those who get a gram is truckload the platform technology that model platform and dynamical assembly are origin Wo Erwo, wo Erwo's new Drive-E engine has only 2 discharge an amount with two 1.5, because this is on 1.5 small quantities,got a gram to also choose with fertile Er Wo Gongping stage is mixed technical 1.5T 3 crocks of engine.
2. is auspicious think this vibration of 3 crocks of machine can be solved
Everybody compares of the care is this 3 crock machine to shake problem especially idle fast shake problem. Auspicious 3 crocks of machine are aimed at this 1.5T technically vibration was done a few optimize.
(1) of engine itself optimize
To solve oscillatory problem, this auspicious 1.5T 3 crocks designed trunnion shaft technically, hang buy to lie between in dynamical assembly at the same time a lot of time were spent on shake, idle of overall assessment result fast vibration is really a lot of better, be the better level in 3 crocks of machine. Do not cross after all or some vibration.
(2) mixture power program
Auspicious predicting future can provide mixture power for 1.5T. Because, of Wo Erwo for this 1.5T 3 crocks of platform had been developed very perfect mix use a system (graph 5) , auspicious should meet move program. In the meantime, auspicious also developed 48V to mix a system gently for 1.5T, use on Bo Rui GE at present (graph 6) . If match,mix after moving, the plan that no matter be auspicious,adopts Woerwo directly (graph 7) , can solve 3 crocks of machine shake problem:
A. Mix the engine after moving not to need idle fast, the engine when jockeying stops directly machine, the idle of 3 crocks of machine fast shake nonexistent.
B. 3 crocks of machine open those who stop systematic work to start time to shake also improved a lot of, the reason is to mix use electric machinery power a lot of bigger than common starting confidential, can draw engine directly 500 turn above, next fire of engine straight contact outputs torque, oscillatory feeling is very slight.
3 crocks of machine can save 3. choice 1.5T cost
(1) reduce investment
Because share platform with Woerwo, invest in the supplier accordingly, treatment is made wait for a respect to be able to share resource, save much investment. (graph 8)
(2) reduce development cost
Share technical platform with Woerwo, economic and many engine base is developed and can match cost. (graph 8)
(3) cost of 3 crocks of opportunity is lower
3 crocks of engine are opposite at because 4 crocks of machine became little a crock, main movement wait with coil of fuel injector, sparkplug, ignition little, accordingly, cost is a few lower for certain. But, as a result of major structural member and periphery function did not decrease actually, still need to increase trunnion shaft, because this cost reduces the level of short of 1/4 (graph the 9 component explosion that are 1.5T pursue) . The cost of 4 crocks of opportunity that thinks 3 crocks of machine comparing measure coequal technology level with the platoon commonly can reduce 10%-15% to control.
Above information consults for everybody, greeting discussion. The friend that is interested in engine can pay close attention to me, the major that can release the engine technology that achieves formerly and property every week is unscrambled, thank support!
