Porsche CEO Oliver Blume recently said in an interview with German media that driverless cars are not the future of the company, so Porsche will not cooperate with technology companies.

engine, is composed of combustion chamber components. Engine Piston Parts,Engine Parts ,Car Engine Parts,Parts Of Engine,Piston Engine Parts ZhouShan HeCheng Machinery Co., LTD. , http://www.hcmarineparts.com
Broome said that the iPhone is suitable for being placed in a pocket and not suitable for being placed on a highway. Porsche does not need to form an alliance with any large technology company. He believes that cooperation is a good way to go if it is not enough, but Porsche does not want to compete for the lead in the driverless field.
Bloom also revealed in an interview that in the near future, Porsche models will be available in all models of the Hybrid, while the Porsche 911 plug-in hybrid version will be available in 2018. The single-way distance in electric mode is 50 kilometers (31.1 miles).
Last month, Porsche announced that it would invest 1 billion euros ($1.08 billion) in the company's largest factory, mainly to expand production facilities and manufacture the company's first all-electric sports car. By 2020, Porsche will launch the Mission E series all-electric sports car with a horsepower of over 600 and a single-way travel distance of more than 500 kilometers.
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed Diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
