Why didn't use turbo the Japanese car
There is concern, Japan and South Korea car line of " T " is not too care about turbo-charger engine,
but is mostly used the normally aspirated engine. Japan and South Korea
car line currently occupy the domestic passenger car market share of
1/3, from their strength, are not difference T technology, but made no
effort to research and development, not a model using the turbocharger
technology. Such as Honda uses i-VTEC engine, Toyota uses the VVTI ,
Nissan adopting advanced VQ engine, modern in China some models also
adopted the technique of CVVT . " Japan and South Korea car line
selection naturally aspirated engine, the primary reasons for its
reliable quality, stable performance, with the same displacement
naturally aspirated engine is turbocharged engine cost savings of
10000 yuan, for better performance. " A well-known domestic engine
company technical director says to the reporter: " Japan and South Korea
of the car is known to cost-effective, must use the engine. " He also
said, most of the domestic car buying the user basically to do
household, rather than the pursuit of extreme sports, naturally
aspirated engine has enough function. In addition, turbocharged engine
basically is cast steel body, which in turn increases the weight of the
engine, and oil saving draw further apart, but also require more
components. " As we all know, more damage to parts, the higher is the
probability of. " He said.
Some consumers believe that,
turbocharged engine to maintain higher, compared with the naturally
aspirated engine repair costs more expensive. But repair experts said,
in fact, turbocharged engine in the repair with the naturally aspirated
engine is not big difference, cause turbocharged engine maintenance
costs, because some of the owners of improper use, turbocharger damage
caused by " replacement, replacement of a turbocharger need thousands of
yuan, consumers think turbocharged engine maintenance costs expensive
". As long as the attention to maintenance and repair, so a few years
not overhaul examples are not uncommon.
