Abstract: A heat exchanger of motor vehicle processes a gas flow including combustion exhaust gas. Combustion by-product deposit build-up within the heat exchanger is reduced by maintaining a minimum gas flow velocity within the heat exchanger by reducing heat exchanger total gas flow cross section to locally increase a gas flow velocity.

Abstract: A spark plug includes a center electrode substantially aligned with a longitudinal first axis and a surface-gap ground electrode radially aligned with the center electrode along a surface-gap electrode second axis substantially orthogonal to the longitudinal first axis and passing there through. The center electrode and the surface-gap ground electrode define a radial spark gap there between. The spark plug further includes a J-gap ground electrode radially aligned with the center electrode. The center electrode and the J-gap ground electrode define an axial spark gap there between. The J-gap ground electrode radial alignment has an angular separation from the surface-gap electrode second axis of no greater than about 30 degrees.

Abstract: A method for controlling operation of an internal combustion engine operating lean of stoichiometry is described. The engine comprises a multi-cylinder direct-injection engine, the engine operative in repetitive cycles each cycle comprising intake, compression, expansion, and exhaust strokes. The method comprises adapting a plurality of fuel injectors to directly inject a first and a second mass of fuel into the cylinders during each cycle. Pressure sensing devices monitor in-cylinder pressure in the cylinders during ongoing operation. The first mass of fuel is injected into one of the cylinders. A cylinder pressure ratio is determined in the cylinder subsequent to injecting the first mass of fuel based upon the monitored pressure. The first mass of fuel injected is adjusted during a subsequent cycle based upon the cylinder pressure ratio.
