Engineering design

Drag Racing is a fast and furious sport. Thousands of horsepower is unleashed in a blink of the eye and must be used safely along the track in seconds. In comparison, an average street car one or two hundred horsepower and takes about 20 seconds to travel the route. Of course, it takes a smart design and manufacturing technology to achieve reliably perform Drag Racing car.

Drag Racer Paul Carey AERO Racing run a Mazda RX-7 in "Super Charged Outlaw" Class Other National Drag Racing Series. AERO Racing teams with an advanced quad-cam V8 Toyota engine to power the RX-7 400m down the drag strip. This is not just an item of interest to them, because it is unique, a Toyota V8 among the legions of American V8, but also enables them to actively 400m sub 8 seconds times.

During the 2008 season were reliability problems with the engine not to let Paul and his team the best performance from your car. The extreme stress on the PSI often charge large gap cylindrical holes in the steel block, leading to expensive and time-consuming engine builds - not to mention the loss of points in the series competitive.

The solution could completely new engine block from a billet of Alumec 89 that is capable of the rigors of competition to develop. But without starting from scratch and reinvent the wheel, or engine also. The next best was a better version of the standard blocks, stronger and more durable, while keeping the production line that has been developed for them, such as the PSI blower, heads, camshafts and bell housing. One of the aspects of improvement was un-needed water cooling channels in the block that is not needed, it is generally less than 10 seconds and remove with methanol fuel cells.

The need for some reverse engineering was evident where. Reverse engineering is a process in which a natural or partially digitized to create the complex shape ACAD (Computer Aided Design) model of advanced computer programs. Finally update again with thisCADmodel engineer, or supplement the original proposal.

Other uses of reverse engineering in cases where there may not theCADmodels or drawings, manufacturing costs of the original parts and must be rebuilt, as new parts for classic cars or machines or additional parts to create just an interface to present pieces. All automakers and even the top teams motorsport use this technology to accelerate the design process.

There are several ways a part of reverse engineering, including the measurement with a ruler by hand. But more sophisticated methods are available and these are CMM (CMM). More specifically, a portable CMM, which was essentially an articulated arm with a probe in the case of the engine block is required. A high precision rotary encoder (high precision position sensor) for all 6 or 7 axes give the part to an accuracy of 0.02 mm can be measured within. You can measure one point on the part of the full three dimensions (X, Y and Z) by simply pressing the probe. Otherwise, laser scanning tools available to allow the full three-dimensional surface to be digitized. This is no longer useful for geometric shapes and contours, as the dashboard of a car for example.

In all cases, an experienced technician who is required to use a high precision machine and motion can give operators a breathing significantly different results. There are techniques to combat this event, such as help with more data points and the average of the results.

A complete overview of the existing engine block functions performed and then used to create an initial CAD model or point cloud model. The tool enables the user space to create circles as points and lines in 3-D model representative of the real part of the surfaces, cylindrical holes and bolt holes. In general, this will not be ready, once an engineer than a whole series of post-processing you are required to create a finished CAD model. This is where an experienced engineer is required to use the measured properties and provide a finished solid model with all dimensions and tolerances specified in detail explained. This whole process requires a high degree of precision and accuracy, the critical geometric tolerances 1500 hp engine deems necessary.

The model can then be at the workshop for manufacturing. High precision machining is another article in itself, but of course is CNC (controlled), all machines in the manufacturing industry used to produce components of high precision, compliments for the accuracy of CMM quite nice.

The finished product is identical to the CAD model of reverse-engineering process are produced. The block is capable warping can be stronger and, more cylinder pressure and temperature reduced. Remember that this engine produces 1500 horsepower from 282 cubic inches capacity! All accessories such as PSI compressor, cylinder head and gearbox bolt back to the original engine. Reliability has also improved and hence the elapsed time has fallen to a personal best 7.367 seconds on, all thanks to some smart technology.
