In the （） pressure charging system the pulse of energy that occur as the exhaust is released from the cylinder to improve the output of the turbocharger.
举一反三
- Turbocharging system may be designed to operate on either the （） or the constant pressure exhaust system.
- In a constant pressure process for a closed system, the internal energy change of the system is equal to the sum of the heat exchanged and the work.
- According to the way the energy of the exhaust gases is utilized， pressure-charging can be divided into two main systems， namely， the constant-pressure system and （）.
- In an engine with air inlet valve and exhaust valve on its cylinder heads the fresh air will enter into the cylinder （） and the gases exhaust （）， there being an adequate overlap between the inlet opening and the exhaust closing.
- Diesel engine air start system check valves are opened by （） A: an air start cam B: cylinder compression pressure C: starting air pressure D: valve spring
