Small Engine Reference Design User Guide Welcome to the Freescale Small Engine Reference Design Kit. This product was designed to be a complete solution for the electronic control of a small engine. Small engines are defined as a one or two cylinder engine for use in anything from a motorbike to a lawn mower to a generator. While the decision was made to address a one-cylinder engine specifically, this design is extremely useful for a two-cylinder engine with little or no modification. Freescale’s concept of creating an engine control kit is intended to enable a market ranging from garage hobbyist to seasoned Tier 1 Powertrain Engineer using Freescale products.
Through the use of this kit, you can create an engine controller specific to a small engine application. Engine control is a discipline that requires intimate knowledge and experience in Chemical, Mechanical, and Electrical Engineering. For those familiar with mechanical control of an engine through a carburetor, the use of this reference design kit can help to advance your knowledge in the electrical area and provide a jump-start for a successful adoption of electrical engine controls to meet new emissions standards. Providing a kit such as this is intended to make semiconductor products from Freescale easier to use.

The user is responsible for providing all input signals, output loads as well as the completed system design and development. This kit should serve as a starting point for the development of an application specific engine controller for a small engine. Example software and documentation are provided to assist in successful design and implementation. It is recommended to have the following skills and experience: embedded C-language programming, analog and digital circuit design and schematic analysis, microcontroller programming, fuel injection system debugging and calibration, and engine test environment experience. Additionally, there is further benefit to experience using the CodeWarrior Development Studio and the Freescale S12(X) microcontroller Units (MCUs). The User Reference Guide provides exercises and references to additional information to reduce the learning curve for inexperienced users.

Freescale’s goal is to enable the small engine market. To clarify this point, the hardware included in this kit can readily be configured and reprogrammed to run an engine. However, it lacks the application specific hardening (EMC, ESD, and environmental areas for example) and implementation optimization that make it a production ready module for any specific application. Further, the free example application software provided is a starting point capable of running an engine. It does not apply any advanced control strategy capable of addressing the pollution concerns and regulations facing the small engine industry. To do this would become application specific to an engine and could not be and should not be implemented by a semiconductor supplier as it is deeply outside their area of expertise. The example application software does show how to use the key functionality in the Freescale products that the kit is based on, which speeds up the development process by showing a working example.

The contents of this kit will save many months of work, even for experienced powertrain engineers just looking to evaluate Freescale products. A system has been created based on a one-cylinder closed-loop engine controller using integrated technology while being cost-effective for the small engine market. Example software is provided that can be customized to run an actual engine that has electronic fuel injection. Documentation is provided to aid in going through the process of developing an application. Finally, information on modifying the design to support the adaptation of the small engine reference design to your application goals.

MANUAL ENGINE COMPONENTS AND FILTERS MAHLE is a leading development partner and supplier of engine components and systems as well as filters for the automotive industry. In close cooperation with engine and vehicle manufactures, MAHLE engineers develop high-quality products worldwide. The same high-quality guidelines also apply to spare parts for the aftermarket. Numerous checks during and after production guarantee the highest quality of MAHLE products. If problems occur during operation, they can usually be attributed to the engine, e.g. incorrect ignition setting, mixture preparation or the electronic control unit. Operating or assembly errors as well as inadequate lubrication and fuels are some of the main breakdown causes. This brochure summarizes typical types of damage. It describes their probable causes and provides information on how to prevent such damage in the future. This should facilitate the search for the possible cause of damage. This information ensures the extensive and reliable functioning of our products and a corresponding long service life for engines. Furthermore, our experts are also confronted with complex damage processes which cannot be explained in this brochure due to space limitations. However, in the event that damage occurs to our products, we will be more than willing to examine them at our facility and to write an expert damage report for you. Please contact your local sales partner or MAHLE representative.
