1.0 Introduction & Objectives
The objectives of this assignment are:
1 To demonstrate skills and competence in modelling 3D CAD solid parts
2 To demonstrate skills and competence in the creation of CAD assembly models
3 To demonstrate skills and competence in engineering drawing
4 To demonstrate skills in the processing and manipulation of CAD images
In summary, the assignment requires the production of:
1. Solid models of all parts shown in Figure 1
2. An assembly model of the complete Engine that is well constrained
3. A detailed part drawing of the Engine Block in orthographic layout
4. An assembly drawing of the complete assembly in orthographic layout
This substantial assignment has been designed on the assumption that you will allocate
typically 15 hours to complete it.
2.0 Description
This engine is a simplified version of a two-stroke engine often found in aero and car
modelling kits. The two-stroke engine is an internal combustion reciprocating engine. The
basic principle of operation of two- and four-stroke engines is essentially the same. These
types of Internal Combustion (IC) engines are used in many engineering applications e.g.
automotive vehicles, ships, motorcycles, electric generators, lawnmowers, chain saws, jet
skis, propeller aircrafts etc.
The IC engine is characterised by an operating cycle having intake, compression,
combustion and exhaust. In a two stroke engine the operating cycle is completed in one
revolution of the crankshaft (i.e. one up stroke and one down stroke of the piston),
contrary to four stroke engines that require two revolutions. This is accomplished by
performing simultaneously the down stroke functions (the end of the combustion and the
intake) and the up stroke functions (the beginning of the compression and the exhaust).
Two stroke engines have the advantage of an increased specific power when compared
to four stroke engines, although they are less efficient and produce larger levels of
pollution.
3.0. Mode of Operation
In this engine model, the piston is connected through the gudgeon pin to the crank drive
system, which comprises of a connecting rod and a crankshaft. The piston is restricted to
a reciprocating up-and-down movement because it fits in a cylinder, with the same
nominal diameter, at the upper part of the block. The crank drive system converts the
reciprocating movement of the piston into rotational movement of the crankshaft. The

Both the cylinder head and crankcase are attached onto the engine block with M3
hexagon socket head screws.
To understand how the two-stroke spark ignition cycle works, we must assume that the ...
Modeling of Micro Turbine for Rapid PrototypingIJMTST Journal
A micro turbine is for harnessing energy from an airflow, which is generated by body motion. The energy is transformed into usable electrical energy and thus providing power for portable electrical devices. The turbine is flown axial and rotates in the same direction independent of the incoming airflow. This paper presents an overview of work performed to date on modeling of micro turbine for rapid prototyping that can automatically take solid models from computer Aided Design data in the form of stl, iges files.
MINIATURIZED CYLINDER HEAD PRODUCTION BY RAPID PROTOTYPINGRodrigo Melo
Abstract. This work shows the development of the design and manufacturing of a very small engine, namely its head.
The engine works under the 4-stroke cycle, therefore having a very complex cylinder head, housing the camshaft,
valves and its auxiliaries (seats, guides, springs), spark plug, inlet and exhaust passages and a coolant chamber. The
geometries, both inner and outer are highly intricate which makes the production of such a part a very difficult job. In
addition, when the engine is very small, as it is the case of this engine, all dimensions are miniaturized therefore
making it extremely difficult to design, cast and finish. The cooling chamber, in particular, has a critical inner core
removal problem due to reduced accessibility, imposing casting limitations. The cores place also a problem of air and
gas removal during metal filling and solidification. Rapid prototyping may be the only solution to build the cores, and
may help in the design and manufacturing phases of the casting tools. 3D printing with a plaster based material as a
rapid prototyping technique presents itself as a tool to drastically reduce the design-development-casting process effort
and time cycle. This technique enables the designer to obtain new moulds for castings on the shortest time possible,
following redesign and new casting simulations. This paper illustrates the various tasks involved in the design and
development stages leading to the production of a running prototype of the cylinder head for this small engine.
This presentation dives into the basics of electronics cooling and demonstrates how engineering simulation software, like SimScale, can help evaluate electronics cooling performance. Additionally, it covers topics like accuracy, accessibility & pre-processing. Learn how computational fluid dynamics and thermal analysis can address issues of thermal management and help engineers optimize designs quickly.
