HKS 700
The HKS 700E is a twin-cylinder, horizontally opposed, four stroke, carburetted aircraft engine, designed for use on ultralight aircraft, powered parachutes and ultralight trikes. The engine is manufactured by HKS, a Japanese company noted for its automotive racing engines.
The HKS 700E has dual capacitor discharge ignition, dual carburetors and electric start. The engine is mainly air-cooled, but with oil-cooled cylinder heads. The OHV pushrod engine has four valves per cylinder, and nickel-ceramic coated cylinder bores. Lubrication is dry sump, with a trochoid pump.
The reduction drive is a choice of two integral gearboxes: the A-type gearbox has a 2.58:1 ratio and can accommodate propellers of up to 4,000 kg/sq.cm inertial load; the B-type gearbox has a 3.47:1 ratio and can accommodate propellers of up to 6,000 kg/sq.cm.
The 700E burns 9 L (2.4 US gal) per hour in cruise flight at 4,750 rpm. The recommended time between overhauls is 800 hours, although this is expected to be increased as experience is gained.
Producing 60 hp (45 kW) at 6,200 rpm for three minutes for take-off and 56 hp (42 kW) at 5,800 rpm continuously, the 700E was designed as a fuel efficient four stroke alternative to the high fuel consumption two stroke engines, such as the Rotax 582.
The company’s owner’s manual disclaimer states:
WARNING! This is a non-certified aircraft engine, the possibility of engine failure exists at all times. Do not operate this engine over densely populated areas. Do not operate this engine over terrain where a safe, power off landing cannot be performed. The operating and maintenance instructions supplied with this engine must be followed at all times. Flying any aircraft involves the risk of injury or death, building and maintaining your own aircraft requires great personal responsibility.
Variants:
700E
Initial version, normally aspirated and producing 60 hp (45 kW) at 6200 rpm for three minutes for take-off and 56 hp (42 kW) at 5800 rpm continuously.
700T
Turbocharged version with a 62.5 mm (2.5 in) stroke and a compression ratio of 8.8:1, that produces 80 hp (60 kW) at 5300 rpm for three minutes for take-off and 77 hp (57 kW) at 4900 rpm continuously. The engine’s dry weight is 57.5 kg (127 lb) equipped with electrical system, electric starter, fuel injectors, gearbox, exhaust system and turbocharger. The initial time between overhauls is recommended as 500 hours, but this is expected to rise with operational experience.

HKS
HKS Co., Ltd. (株式会社エッチ・ケー・エス Kabushiki-gaisha Ecchi Kē Esu) was formed in 1973 by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Goichi Kitagawa, while the start up capital was supplied by Sigma Automotive (hence the name HKS). The company began operations by tuning gasoline-powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan. Their goal was to design and build high performance engines and components that major OE (original equipment) manufacturers could not or would not produce. In July 1974, Hasegawa engineered and built the first commercialized turbocharger kit for passenger automobiles; since then developing turbocharger upgrades and bolt-on turbocharger kits that subsequently became the core business of HKS. Hasegawa also created the first commercially available electronic turbo timer and boost controller.
HKS is a publicly traded company with an international sales and distribution network spanning Asia, Europe, Australia and the Americas to support its customer base. The main manufacturing and R&D facility is at the foot of Mount Fuji. Subsidiary companies have been established in California (HKS USA), Cambridgeshire, England (HKS Europe), and Bangkok, Thailand (HKS Thailand). HKS USA, established in 1982, shut down operations in 2011 electing instead to use wholesale distributors to handle their supply chain in the USA. Motovicity Distribution was selected as the North American warehouse for HKS where a full inventory of products is maintained for HKS’ North American customers.
The company also produces the HKS 700E aircraft engine, under its subsidiary, HKS Aviation. And also produced a 600cc Speedway cycle engine.

Hirth
Hellmuth Hirth (1886 – 1938) worked for a short time as a foreman at aviation pioneer August Euler in Darmstadt. However, since Euler had difficulties with his Voisin-type flying machine, Hirth returned to Stuttgart to build himself a Blériot machine. Because of the too weak engine, this did not go beyond small aerial jumps, causing Hirth to go to Vienna to fly the Etrich Taube together with Illner. He then became designer at Rumpler and Gotha, before turning to engine development.
