Axi-symmetric stall, more commonly known as compressor surge; or pressure surge, is a complete breakdown in compression resulting in a reversal of flow and the violent expulsion of previously compressed air out through the engine intake, due to the compressor's inability to continue working against the already-compressed air behind it.
Problems were encountered with the Kawasaki design, particularly with engine cooling, and the Mitsubishi Ki-30 received the production order. In spite of this, the pressing need for more aircraft in the Second Sino-Japanese War , which had started at full scale in July 1937, resulted in the Ki-32's entry into production as well, 12 months ...
The engine was a straight twin, two-stroke, air-cooled, oil-injected, dual rotary disc valve.The engine's ignition air supply began in an air filter canister below the seat and was pulled through a large plenum chamber just above the transmission and behind the cylinder head then downward into the two internal passages leading to the carburetor housing feeding the carburetors.
Exhaust system backfires occur in engines that have an emission system malfunction, like an air injection system diverter valve problem, an exhaust leak, or when the catalytic converter has been removed. In some high-performance vehicles, when a driver shifts up and lets off the accelerator, the engine has a moment of running rich. This causes ...
After the war, along with the Allied arms-limitation agreement in 1912, Kawasaki faced a huge decline in shipbuilding. In 1929, the Depression caused a large amount of financial problems with the company. During World War 2, Kawasaki was a major builder of combat aircraft like the Ki-61, which killed many Allied aircrew.
The engine was advanced for its time, with features normally seen on race bikes: two-cylinder, two-stroke, air-cooled, oil injected, dual rotary valve.While other manufactures had utilized the advantages of rotary disc valve induction on small single-cylinder machines, only Kawasaki and Bridgestone produced twin-cylinder machines.
It was an effective design, but suffered from engine shortages and reliability problems. These problems led to the development of an improved model, the Ki-61-II (later Ki-61-II-KAI), powered by the improved 1,120 kW (1,500 hp) Kawasaki Ha-140 inverted V-12 engine, which was heavier than the Ha-40 it replaced. Maximum speed increased from 590 ...
Kawasaki swapped the traditional 4-4 exhaust (available on Z1 and KZ900) for the 4-2 Jardine exhaust (which came standard on the KZ900B) on the LTD and quiet and restrictive muffler on the 1000 A1 and A2 as shown in the top photo in this article. The KZ1000 came with either a chain drive or shaft drive in 1979 and 1980 named ST and SHAFT ...
