Abstract
High-pressure multi-hole injectors for direct-injection spark-ignition engines offer significant benefits in terms of fuel atomization, as well as flexibility in fuel targeting by selection of the number and angle of the nozzle’s holes.
Unfortunately, little data exists for injector-body temperatures representative of engine operation with various fuels Bio-derived fuels further complicate the situation, presenting the requirement to manage fuel flexibility. The physical/chemical properties of bio-components can differ significantly from gasoline. Consequently, it is important to study their effects in direct comparison to liquid hydrocarbons. Authors present results from an optical investigation, using high-speed imaging and droplet sizing, into the effects of fuel properties, temperature and pressure conditions on the extent of spray formation.
