A Study On The Engine Performance And Emission Characteristics Of Gasoline Engine Using Dimethylfuran-Based Blends

Tác giả: NGUYEN DANH CHAN

Lĩnh vực: Mechanical Engineering

Nội dung tài liệu: Nghiên cứu này tập trung vào việc đánh giá hiệu suất động cơ và đặc tính khí thải của động cơ xăng khi sử dụng các hỗn hợp nhiên liệu gốc dimethylfuran (DMF). Đề tài xem xét các hỗn hợp DMF với xăng RON95 ở các tỷ lệ khác nhau, từ thấp đến cao, nhằm cung cấp cơ sở ban đầu cho việc ứng dụng nhiên liệu này tại Việt Nam trong tương lai. Nghiên cứu bao gồm cả phương pháp mô phỏng và thực nghiệm để đánh giá các thông số kỹ thuật và khí thải.
