Kat's 1160 300 Watt Magnum Handi-Heat Magnetic Heater

A magnetic heater is an electric heater that heats the engine or transmission of a vehicle to give quicker starts and protects your engine from damage that can occur during cold weather starts. Warmed engines also deliver better fuel economy, plus improves oil flow to provide better lubrication to the engine, which reduces wear and increases engine life. Oil and transmission fluids thicken and do not circulate well at cold temperatures. Magnetic heaters transmit heat continuously to keep oils fluid, giving you instant lubrication when starting your engine. The Magnum is an upscale version of the magnetic heaters. It features two powerful magnets and expanding heating surface. Its larger size makes it ideal for use on trucks, diesels, and farm machinery.

Unfortunately, many bear the misconception that SH engines run very hot and thus wear out faster. The truth is that these are incredibly powerful and reliable engines. In fact, they are currently the largest exposures of RC on road, off road and competition engines in Asia, displacing the previously popular Toki and Team Infinity branded engines. However, to the inexperienced hobbyist, they may experience overheating problems with their SH engine. This is because the factory needle settings may be incorrect. Apparently, the default needle settings for the SH .21 and .28 engines are 4.75 turns out for HSN and 3 turns out for LSN - both from a fully closed position. My SH engine arrived with a very lean LSN setting. Consequently, I experienced problems starting the engine, as well as difficulty getting the engine to idle. If I did not adjust the trim or hold the throttle, the engine would shut off. I did a check on the exhaust and found that the fumes were grey or transparent and did not splutter unburnt fuel. The engine also hit temps of over 270 f. I proceeded to richen LSN in gradual increments and I hit the right tune after richening about .45 turn. I just finished my 5th tank and temperature does not exceed 225 f, like any other big brand engine described in RC car engine break in instructions found online. If you own a SH engine that is running hot, do try the tips I described in this post. If you have a question or feedback on SH engines, do leave me a comment on this post. Cheers!

Plexiglass with bolts pinch together the various pieces and rubber washers ensure a good seal. Copper, being very thermally conductive makes a good choice to exchange heat into and out of the working gas (air) inside.

The book covers the various approaches to modeling the in-cylinder processes such as mixture formation, combustion and formation of exhaust emissions in diesel and gasoline engines. Due to their complexity, emphasis is put on multi-dimensional spray, combustion and emission formation models. However, phenomenological as well as zero-dimensional thermodynamic models, which are still widely used in engine development because of their computational efficiency, are addressed as well. Example calculations of each model type are compared with corresponding experimental data – represented in diagrams as well as in images resulting from modern optical measuring techniques – in order to discuss the capabilities of today's simulation models and the shortcomings that still exist either because of oversimplifying assumptions or insufficient knowledge. Readers achieve an overview of the most important simulation models describing the in-cylinder processes of internal combustion engines and gain insights into which modeling approach is appropriate for a specific problem.
