This paper describes the analysis of the flow in the intake manifold of a V6 gasoline engine performed using WAVE 1D engine cycle simulation program alone first, and then using WAVE coupled with 3D CFD VECTIS. The work shows how modeling in 3D selected components of the inlet manifold embedded within the 1D flow network leads to improvements in prediction accuracy.
The main purpose of this work was to improve the WAVE model of the V6 3.2l engine, scheduled for installation in the GTA version of the popular Alfa Romeo 156 vehicle. Moreover, this work was also part of a comparative study between two intake manifolds differing in shape and volume.

2001 ENGINE PERFORMANCE' 'Basic Diagnostic Procedures Ignition Coil Test (Accord 2.3L & CR-V)
1. Turn ignition off. Remove distributor cap, rotor and leak cover. Remove primary leads from ignition coil. Using an ohmmeter, check primary resistance between ignition coil terminals "A+" and "B-". See Fig. 12 . Resistance should be as specified. See IGNITION COIL RESISTANCE table. 2. Check secondary resistance between ignition coil terminal "A+" and secondary output terminal (ignition coil tower). See IGNITION COIL RESISTANCE table. If readings are not as specified, replace ignition coil.
