NEW ELECTRONIC GAS CARBURETORS FROM CCC TARGET EMISSIONS AND FUEL EFFICIENCY

摘要

The Carburetors are Designed for Small Gas Engines Ranging from 50 to 500 hp (37 to 372 kW) Two new models of electronic gas carburetors from Continental Controls Corp. (CCC) target operators' needs to meet emission requirements and increase fuel efficiency while reducing engine maintenance. The carburetors are designed for small gas engines ranging from 50 to 500 hp (37 to 372 kW). According to the company, the key to the carburetors' approach is threefold: 1. Integrated into the carburetor's electronics is a controller to support a wide-band oxygen sensor located in the engine's exhaust stream, which provides stable and reliable feedback to the carburetor for air/fuel ratio control. 2. Integration of an advanced solenoid actuated fuel valve, which operates on a patented variable pressure control concept with the pressure control setpointed based on the input from the wide-band oxygen sensor. 3. Utilization of a mixing Venturi that replaces the traditional diaphragm/spring combination normally used in carburetors. The Venturi also provides mixing of air and fuel, which allows the engine to run leaner before reaching a lean misfire condition.
