Approach for Improved Fuel Vaporization in a Directly Injected Internal Combustion Engine |
摘要 |
A system and a method of facilitating fuel vaporization in a directly injected internal combustion engine are provided. As one example, the method comprises: closing an exhaust valve of the cylinder; opening an intake valve after the exhaust valve has closed; moving a piston of the cylinder away from top dead center between the closing of the exhaust valve and the opening of the intake valve to expand the cylinder volume and reduce a pressure within the cylinder to below a pressure of an air intake manifold of the cylinder; and initiating an injection of fuel directly into the cylinder via an in-cylinder injector after the exhaust valve has closed.
