Yuchai
Features & Benefits
Designed and developed on ECI (Econtrols) technology platform to provide the flexible power solution for buses and coaches, they share main components and parts with diesels versions, while inheriting all the super advantages.
Quality imported electronic gas feed system, ignition system and engine management system kits.
Platinum electrode spark plug- Give the most efficient combustion and extend performance life.
Specifically built intake & exhaust system, fuel system are designed and configured for gas engine.
Oxygen sensor- Achieve precise control over the air/ fuel ratios, providing the best fuel economy while reducing emission dramatically.
Closed-loop control system-Achieve closed-loop performance across wide operating range and self-diagnostic function.
Intelligent electronic control system- Complete in functionality.
Smooth gentle combustion- Give you the best comfort ride with less noise and vibration.
Oxidation catalyst- Easily meeting Euro 3 levels of performance, and be able to move to Euro 4, Euro 5.
Highly human-oriented and easily interchangeable design, allowing for ease of maintenance.
