Group 3 - GM V-6 Engine 1
GM V-6 Engine
In order to reverse engineer out motor we plan to start by taking photos and recording the position of everything on the motor, as is. We will start by removing any subsystems such as electrical wiring harness, air intake system, exhaust systems, starter motors, charging systems, and the ignition system if they are present. After that we should be left with the block and the heads. We will then remove the pistons by unscrewing the nuts for the rod caps with a ratchet set then hit the rod bolts with a brass hammer into the rod body, then to remove the cap rock it back and forth, we should remove half a baring shell, that we will measure and record its position on the rod charnel of the crank. We will then place a protector sleeve over the rod bolts to prevent damage to the crank shaft and the cylinder walls when the piston comes out. Then take 2 long head blots and put them in by hand neat where the piston you are removing is going to come out then place a rubber band that will have some tension between the two about an inch or two away from the head, this should prevent the piston from dropping when you remove it, you may also use a thin wire or some string. Before we actually remove the piston we are going to want make sure the ridge build up is not going to make the piston removal harder, if it is we will need to clean the ridge with a razor blade. We will then move the rod charnel of the crack to the center line of the cylinder bore of the piston we are planning on removing then take a wooden dowel about the size of a broomstick and 2ft long and place it on the back of the piston to the side of the crank shaft. Then hit the dowel several times with hard hits to remove the piston, make sure someone is ready to catch it should the rubber band fail. It the piston is so stuck you need break the dowel, replace it with a metal rod and do the same with harder hits. We can then remove the piston make sure not to damage the cylinder wall with the edges of the connecting rod. Then place it in a bag with a number on then place a piece of tape with a matching number on the cylinder it came from. We can assume that all the pistons have the same dimensions but we will still record the position of each piston Then we will take apart the valve train.
In order to successfully dissect our automobile engine, we have decided to give certain positions to each person in our group. With these positions well be able to identify the specific roles of each person in our group. But even though a specific role is given to a person, we will all try to work an equal amount on the project so that we produce a report of high quality. The roles of each person are as follows:
Noor Jariri and Tanner Kahm- Technical Experts
• Makes sure that all necessary tools and equipment needed to dissect the engine are accessible.
• Will provide the information of the more in- depth characteristics of the engine.
• Makes sure that the information in reports are professional and technically accurate.
Matt Egan- Technical Report Editor
• After whole technical report is compiled, Matt will be the primary editor or the report to ensure quality of content and check for grammatical mistakes.
Jasmine Lawrence- Project manager
• Will make sure that the group stays on task and completes assignments on time.
• Provides an order of how and when each gate will be completed.
Samuel Kim- Communication Liaison
• Primary point of contact.
- E-mail- firstname.lastname@example.org
- Phone number- 845- 645- 0702
• Keeps track of all group meetings and will send out reminders or deadlines.
• Taking notes of on dissection process and makes sure that each member has the information available.
In order to complete the project in a timely fashion we have decided to meet twice a week on Tuesday and Thursday in the Capen Library or in the lab located at Furnas 621. If more meetings are needed we will schedule them accordingly with everyone’s schedule. The plan during the labs is to dissect the engine as efficiently as possible while learning about each subsystem noted in the Product Proposal (rotating assembly, valve train, energy transformation systems, engine control systems). We will be starting with the top of the engine taking apart each section of the head and then the block so we can view the inner parts of the engine. First, we will look at the main rotating assembly and how the crankshaft works with the connecting rods, pistons. After this, we will move to the valve train and look at the camshafts, valves and several other components in this system. And then we will move on to observe the energy manipulation components of the engine like the water and oil pumps and alternator. During our meetings and time in labs, we will complete the dissection of the engine while learning about each system and subsystems as well as re- assembling the engine in the state given to us. If there is a conflict within the group, we will all come together and discuss the issue that is at hand and we will handle it in a fair, democratic way that would hopefully do away with the problem within the group.
The following outline is a schedule of our planned meetings:
• Gate 2: Due 10/26/11
October 11th , 13th , 18th and 21st
• Gate 3: Due 11/14/11
November 1st , 3rd and 10th
• Gate 4: Due 12/2/11
November 17th (21st if necessary) and 29th
• Gate 5: Due 12/16/11
December 6th and 8th
At each of these meetings we will work to accomplish as much as possible, especially in the lab, so that we can meet the requirements of each gate in a timely fashion. We will continue to communicate effectively via email, text messaging and phone calls to solve any possible conflicts as well as answering any questions that may arise in the whole project.
The General Motors Vortec 4300 engine was typically an engine design for small to medium sized trucks, sport utility vehicles, and vans but also made some appearances in large passenger sedans. The wide range of vehicles it was used in portrays the engine's versatility in the automobile market. Being put into generally larger vehicles, the engine has a higher output (around 200 horsepower depending on the model) than smaller four cylinder engines. This shows that the intended use of the engine was to provide sufficient power to these larger vehicles. The engine also had a high specific torque in order to haul loads in the given vehicle as well as to provide an acceptable rate of acceleration in heavier consumer vehicles. This engine was designed for use in typical consumer automobiles, but also had some usage in different professional machinery. This is evident in the tasks it can perform better than some other engines, such as towing or hauling loads. Due to the Vortec's high torque, along with its' wide torque band, the engine can handle extended periods of high load such as those experienced during towing. The engine also does this while being more economical than a typical eight cylinder engine.
