Vikings "Honda based" TURBO is a turbo engine reimagined.


One previous disadvantage of turbo engines was that by sending high-pressure air into the engine, the temperature and pressure within the engine would rise, resulting in knocking. The Viking TURBO employs direct injection technology to inject fuel directly into the cylinders, lowering the temperature within the cylinders by the gasoline’s vaporization heat. High tumble intake  and "tumble flow maintaining pistons" allow fuel to be quickly and efficiently burned. Due to the cooling effect of direct injection and rapid combustion by high tumble flow, knocking no longer occurs.


Liquid-cooled Exhaust Manifold built in to Cylinder-head
Turbochargers use high-temperature exhaust gas from the engine’s combustion chamber to send air into the engine. As turbocharged engines have high torque, the exhaust gas from the combustion chamber can exceed 1,000ºC. Cooling jackets within the cylinder head reduce exhaust gas temperature to an optimal level before it enters the turbocharger. Thus the turbocharger’s reliability, is increased. 


This 1.5-liter four-cylinder uses a small diameter turbo, high-tumble intake port, direct injection and sodium-filled exhaust valves to provide 200 horsepower and 460 pound-feet of torque at the propeller. Despite its turbo this engine delivers a broad, flat torque band by way of its variable valve timing and electronic wastage.

Inline engines have their own challenges with cowling installations / design.  The engines are tall and narrow.  In order to get an aerodynamic shape the following "tricks" are used during the cowl design.  

  1. Use a relatively large spinner
  2. Design cowl to clear the majority of the engine.
  3. Make false inlets, etc. for  protruding items, such as the top mounted fuel pump.  
  4. Provide a centered cowl drop-down in order to clear the oil pan and to provide cowl exit air.
