- 摘要：
- Experiments are conducted on a 4-cylinder direct-injection diesel engine using ultralow-sulfur diesel as the base fuel and diglyme as the oxygenate component to investigate the particulate emissions of the engine under five engine loads at two engine speeds of 1800 rev min1 and 2400 rev min1. Blended fuels containing 5%, 10.1%, 15.2%, 20.4%, 25.7% and 53% by volume of diglyme, corresponding to 2%, 4%, 6%, 8%, 10% and 20% by mass of oxygen, are studied. The study shows that with the increase of oxygen in the fuel blends, smoke opacity, particulate mass concentration, NOx concentration and brake specific particulate emission are reduced at the two engine speeds. However, the proportion of soluble organic
fraction is increased. For each blended fuel, the total particle number concentration is higher while the geometric mean diameter is smaller, compared with that of ultralow-sulfur diesel, though the particle number decreases with the oxygen content of the blended fuel. Furthermore, the blended fuels also increase the number concentrations of particles smaller than 100 nm.
