LPG elektronik kontrol ünitesi(ECU), motorun değişik yük ve yol şartlarına göre sensörlerin ve veri sinyallerinin otomatik diyagnostiğini yapar, en iyi karışım miktarını hazırlamak ve bu hazırlanan karışımı en doğru zamanda emme manifolduna iletmek için enjektörleri kontrol eder. LPG yakıt miktarının hazırlanması için LPG basınç sensörü, LPG ısı sensörü, motor devir sensörü ve benzin enjektörlerinden alınan sinyaller LPG elektronik kontrol ünitesine iletilir. Bu çalışmada mevcut bir LPG sisteminin bileşenleri incelendi. Sistemin çalışma aşamaları dikkate alınarak, LPG sistemine ait elektronik kontrol ünitesinin işlevsel özellikleri tahlil edildi ve analiz edilen veriler ışığında yeni bir kontrol ünitesi tasarlandı. Tasarlanan yeni LPG elektronik kontrol ünitesinin 4 silindirli, buji ateşlemeli bir motor üzerine yerleştirilmiş 4 adet LPG yakıt enjektörünü ne şekilde kontrol ettiği gerçek yol şartlarında test edilerek gözlemlendi. Test aracının performansı, yakıt ekonomisi ve aracın tasarlanan LPG elektronik kontrol ünitesiyle olan uyumu farklı yol, sıcaklık ve hız koşullarında gözlemlenerek ürünün uygunluğu kontrol edildi.
The LPG electronic control unit (ECU) automatically diagnoses the sensors and data signals according to the engine’s different load and road conditions, preparing the best amount of mixture and controlling the injectors to transfer this prepared mixture to the absorption manifold at the right time. Signals from the LPG pressure sensor, the LPG heat sensor, the motor rotation sensor and the gas injectors are transmitted to the LPG electronic control unit for the preparation of the amount of LPG fuel. In this study, the components of an existing LPG system were studied. Considering the work stages of the system, the functional characteristics of the electronic control unit of the LPG system were evaluated and a new control unit was designed in the light of the analyzed data. The new designed LPG electronic control unit was observed by testing in real road conditions how it controlled the 4 LPG fuel injectors placed on a 4-cylinder, bush-burning engine. The performance of the test vehicle, fuel savings and the conformity of the vehicle with the designed LPG electronic control unit were monitored in different road, temperature and speed conditions and the suitability of the product was checked.
The LPG electronic control unit (ECU) performs automatic diagnostics of sensors and data signals according to the different load and road conditions of the engine, controls the injectors to prepare the best mix quantity and deliver the prepared mix to the intake manifold at the right time. In order to prepare the amount of LPG fuel, the signals received from LPG pressure sensor, LPG heat sensor, engine speed sensor and gasoline injectors are transmitted to LPG electronic control unit. In this study, components of an existing LPG system were examined. Taking into consideration the operational stages of the system, the functional characteristics of the electronic control unit of the LPG system were analyzed and a new control unit was designed in the light of the analyzed data. The new LPG electronic control unit, designed to control 4 LPG fuel injectors installed on a 4-cylinder spark plug ignition engine, was tested under real road conditions. The performance of the test vehicle, fuel economy and the compatibility of the vehicle with the designed LPG electronic control unit were observed in different road, temperature and speed conditions and the suitability of the product was checked.
