KCTCS Course No. KCTCS Course Title DIT 112 Diesel Engines</p><p>Introduction/Conte This lesson will instruct the student on how to perform intake manifold pressure xt (boost) test, and determine needed action.. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in a Diesel Repair Facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident or create customer satisfaction issues.

Tell students to Install a pressure gauge to the fitting in the turbocharger outlet. They should then install another pressure gauge in the intake manifold. Have them operate the engine at rated RPM and load, and record the readings on the two gauges. Let them know that if the differential pressure is greater than 21 kPa [3 psi], they should check the charge air cooler for plugging. Tell them to clean or replace if necessary. Inform students on how to perform an Intake Manifold Temperature Check. Have them install a temperature gauge in the intake manifold. Tell them to lock the fan drive in the ON mode to prevent erratic test results. Explain that this can be done by installing a jumper across the temperature switch or supplying shop air to the fan. Have them refer to the fan drive manufacturer for lock-up procedure. Let them know that some trucks have a manual switch that will lock on the fan. Tell students to operate the engine at rated RPM and load. Have them record the intake manifold temperature. Instruct them to measure the ambient temperature at least two feet in front of the vehicle. Let them know that the maximum temperature differential must not be greater than 25°C [45°F]. If the temperature differential is greater than 25° C [45° F], tell them to check the charge air cooler for dirt and debris on the fins, and clean as necessary. If the problem still exists, tell them to check the cooler for internal contamination or plugging. To check the charge air cooler for cracked tubes or header, instruct students to remove the inlet and outlet hoses from the cooler. Remove the charge air cooler. They should then install a cap over the outlet side of the cooler, and install a pressure gauge and a shop air supply line to the inlet side of the cooler. Tell them to apply 276 kPa [40 psi] of air pressure to the cooler. If the pressure drop is 35 kPa [5 psi] or less in 15 seconds, let them know that the cooler is okay. If the pressure drop is greater than 35 kPa [5 psi] in 15 seconds, tell them that the charge air cooler must be repaired or replaced. Refer to the manufacturer for repair instructions.</p><p>Applications/Practice 1 Refer to content Evaluation and feedback Prior to Testing or Lab Work Objective 1. / Formative assessment / Instructor will observe students as they practice the procedure to assure correct procedure and safety practices are being followed. A checklist will be utilized to chart 1 student progress on the task. Questioning techniques will be utilized as necessary to demonstrate student comprehension / Adaptations and/or accommodations for special needs students will be added if required.</p><p>STUDENT ASSESSMENT: (Assess student progress with performance criteria.) Objective 1 / Summative assessment / written test questions on stated objective / adaptation and / or 1 accommodations for special needs students will be added if required</p><p>IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)</p><p>REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)</p>
