Custom Engine Rating Application for Fortune 100 Natural Gas Engine Manufacturer


Engineers at a leading engine manufacturer faced a common struggle — managing and distributing complex data sheets containing critical calculations for the sale of natural gas engines in mechanical drive and electric power generation applications to dealers/purchasers doing business on a regional and global basis. This method, used for engine sizing, became unwieldy with multiple engineers updating versions concurrently, leading to inaccuracy and inefficiency.


CSE Software addressed this challenge by developing a custom engine rating application. The application aimed to store, maintain, update, and display data and calculations, streamlining the engineering and customer process. Following user input, a comprehensive data sheet is generated, providing in-depth insights into engine performance under specific conditions. The application’s end-users, including dealers and customers, utilize it to size engines for specific site applications, ensuring the right engine for each customer.


CSE Software collaborated closely with the manufacturer’s engineering team, translating their complex formulas into a user-friendly interface. The data, crucial for engine sizing, remained under the ownership and management of the manufacturer’s engineering team.

CSE’s capabilities in this application development process included: scope & requirements, development, testing, production delivery, application maintenance, and ongoing help desk support.
