Abstract: A pressure sensor (40) is mounted in an internal combustion engine (1) for determining induction pipe pressure (P) in a connecting line (30) between the induction pipe (5) and the fuel pressure regulator (35).

Abstract: Intake manifolds for an internal combustion engine and methods of using the same are disclosed. The intake manifolds accommodate the introduction of exhaust gas that has been recirculated from the main exhaust gas stream. The exhaust gas can be introduced into the intake manifold through aerodynamically shaped members that are located inside the manifold. Alternatively, the exhaust gas can be introduced into the manifold at or near the intersection of the primary runners and the plena, or the exhaust gas can be introduced into a mixing chamber located between the primary runners and the plena.

Abstract: A system and method for controlling an internal combustion engine to reduce or eliminate formation of EGR condensate monitor current ambient and operating conditions to determine whether conditions are favorable for condensation of EGR gases, and control the engine accordingly to avoid condensation, preferably by increasing the intake manifold temperature. The intake manifold temperature may be increased by redirecting some or all of the EGR flow to avoid the EGR cooler. Alternatively, or in combination, some or all of the charge air may be redirected to bypass the charge air cooler and/or redirected from the outlet of the turbocharger compressor to the intake, effectively increasing the intake air temperature and resulting in a corresponding increase of the intake manifold temperature. Conditions favorable for condensation may be determined based on engine speed and load, ambient temperature, manifold pressure, scheduled or actual EGR flow rate and scheduled or actual air/fuel ratio.
