Tóm tắt
Cháy bằng nén với nhiên liệu xăng (GCI - Gasoline compression ignition) là một phương pháp tổ chức quá trình hình thành hỗn hợp và đốt cháy tiên tiến với tiềm năng cải thiện tính hiệu quả sử dụng nhiên liệu và giảm lượng khí thải từ động cơ đốt trong. Chiến lược phun với điển hình là thời điểm phun có ảnh hưởng lớn đến quá trình hình thành và phát triển cháy của động cơ GCI, kiểm soát sự hình thành cháy khuếch tán. Để xem xét thời điểm phun thay đổi để đạt được hiệu quả cao trong chế độ tải trung bình đặc trưng (IMEP 5 bar). Ở nghiên cứu này, tác giả khảo sát thời điểm phun chính thay đổi với các điều kiện vận hành được giữ không đổi: giữ cố định tỷ lệ phun 30%-70%, thời điểm phun mồi -35 CAD ATDC, tốc độ quay động cơ 1500 vòng / phút, nhiệt độ khí nạp 165 oC, áp suất nạp 1 bar và áp suất phun 400 bar. Thông qua kết quả thí nghiệm, các ảnh hưởng đồng thời của quá trình cháy với ngọn lửa lạnh và tia phun của lần phun chính thâm nhập được đánh giá có ảnh hưởng đến tốc độ cháy của quá trình cháy chính. Ngoài ra, nhiệt độ cháy cực đại, tốc độ tăng áp suất trong xy lanh và hiệu suất cháy, hiệu suất chỉ thị của động cơ cũng được đánh giá để tìm ra được góc phun sớm tối ưu với chế độ vận hành này của động cơTài liệu tham khảo
