1 Introduction
The study highlights on the design and production of chosen product Diesel Engines. Engine
refers to the kind of machine that converts power into mechanical energy. It is also termed as
motor and different engines have different kinds of characteristics in it. It can been seem that
heat is produced by heat engine with the help of burning resources. Similarly, electric engine
converts electric energy into kinetic motion (Carpenter et al. 2012). In automobile industry,
engine plays a vital role in attaining high profitability. However, various types of engines that
exists in automobile industry are diesel, heat, petrol engines etc. Basically, the industry focuses
on the engines as they are considered as the basic component in manufacturing a product. It has
been noted from various researches of this field that engines produced by engineers ha huge
significance and hence one of the breakthroughs has been done by Rudolf Diesel in the year
1892.
In this paper, several kinds of heat engines are considered and its main purpose in automobile
engineering field are illustrated. It has been seen in the past that persons employs temporary as
well as ordinary machines for designing and manufacturing a product. Modern equipments were
introduced after the period of industrial revolution that involved automobile engines. Automobile
engines includes diesel, heat, mechanical engines. All these types of engines are categorized into
two types that includes – mechanical or automotive. These two types of engines are basically
internal combustion and external combustion engine. Though the external structure of these
engines was similar, they vary in terms of fuel consumption. The consumption of fuel occurs in
diesel engines internally. While external combustion machines are specially applied in
locomotive as well as in marine vehicles by utilizing gas or liquid fuels. Moreover, it has been

well known that internal incineration engines are less flexible than external combustion engines
even after getting initial torque. Internal combustion engines basically employs volatile fuels
such as diesel or petrol. Moreover, this internal combustion engines are used in automobiles and
its has huge significance in this industry as it is cost as well as thermal efficient. Internal
combustion engines are mainly automobile engines. Therefore, the features as well as the
functions of IC engines are explained below.
In case of diesel engine, the compressed air as well as reactant fuel has been employed under
high pressure and high temperature into combustion chamber. On the other hand, different types
of engines are segmented based on the design, strokes and total fuel used in it. The major
components of engines include cylinder block, piston ring, connecting rod and head. The
temperature of the engine is usually evaluated by the size, fuel utilization and type of the engine.
Several varieties of engine that exist in the automobile industry is based on the cylinder, total
intake of fuel etc. The characteristics of diesel engine is illustrated below.
 The ratio of air to fuel in the engines is 14.7
 The temperature that it can intake is around 180-210 degree Celsius
 The compression ratio of regular fuels and premium fuels is around 9 and 10 respectively
 The intake pressure is around 0-6 bars
 The thermal efficiency of the engines is near about 39%
 Work done by engines refers to net power of engines output.

Assessing the needs of the consumers
It is vital for every organization to assess the needs and preferences of the customers in order to
attain higher profitability. Various strategies or steps are implemented for each segments at
which the producers mainly focus on for meeting the needs of the customers. This improves the
sales performance of the organization as they manufacturers designs the product accordingly.
The management of the firm follows certain steps in order to tackle the requirements of the
customers. These includes-
 Interviewing the customers
 Visiting the customers
 Obtaining feedback from the customers
 Focusing customers groups
 Providing warranty forms to the customers
Interviewing the customers
Customer interviews facilitate the firms in focusing on the needs of the customers and obtain
feedback in order to produce the best product. The management of the organization takes the
interviews of the customers and hence the data gathered from the respondents helps in designing
the product according to the customer’s preference.
Customers are also interviewed through telephone or internet and this procedure needs good
communication skills of them. The company interviews all types of customers in order to obtain

questionnaires for covering up the minute details in relation to this product. The production
department gains huge benefit as this procedure helps them in gathering the feedback and work
according to it. The questionnaires have been prepared in relation to the power of engine,
framing issues etc. After acquiring the data from the interview, the firms then filter and segment
it according to the views of customers. In contrast to this, the customers then divides it into
Essential, Needs and Extra.
Visiting the customers
It is vital for every production company to visit the customers and making note of their needs
and preferences. It has huge significance in this industry as it helps in attaining competitive
advantage over their rivals. The leading firms in this industry apply this strategy in order to make
sure that the expectations of the customers are met. Additionally, the needs of the customers are
analyzed in proper way and are kept in records (Shi. and Zhou 2013). This records helps the
company in enhancing their service from the view point of customers satisfaction. Good
communication is also considered as the main factor that is involved in this process so that the
firms can answer the impractical questions that might be asked by the customers. There are few
customers that comes with the question that is related with production such as operations,
efficiency and procedure applied in manufacturing the product. Therefore, interaction with the
customers facilitates the companies in improving the quality and design of the product.
