INTRODUCTION:-
FIAT is one of the leading Automobile Industry in the world. The Engines and Transmissions produced by FIAT has been appreciated globally in terms of its quality, performance and efficiency. It is said that every third car in the world has FIAT’s Engine.
The plant capacity is to produce 3.5 lacs power train and 2.5 lacs car per annum. Though the manufacturing system is highly automated with highly skilled manpower, the FTQ (First Time Quality) percentage is 97.89% that means there is a rejection of around 2.11%.
Our project is solely related to Introduction of New Product (EURO-5 ENGINE) and to reduce the Bottleneck time of Trimming Assembly line, to reduce N.V.A (Non Value Added) activities and Insaturation present in line and to increase the overall production. Simultaneously reducing the cost per engine.
The Company has defined some targets in terms of quality and performance, so that every single unit has to pass through various quality checks to assure the quality of the product delivered. So keeping in mind all these targets we tried to reduce as much waste time as we could.

PLANING OF ACTIVITIES:-
Keeping in mind the vastness of the activities it was important to go for procedure which would fetch us the most desired results efficiently and effectively. We tried to considered all the factors by which we can execute are project without errors.
Planning: It involves defining the problem, collecting data, selecting theme, defining targets and analysis.Bottleneck time of Trimming line was very high(0.85). Due to this insaturation and N.V.A activities in line were very high.We thoroughly analyzed the Activity breakdown sheet and noted all the activities performed on every station in line.
Do: Implementing things or changes finalized in planning section. Distribution of some activities on other O.P Stations and elimination of various N.V.A activities was done.
Check: After ‘Do’ operation, running experimentation, feedback is to be taken to analyze and evaluate the thing implemented.
Act: It involves standardization, lesson learned and horizontal development.

Project 1
SAFETY Improvement
FIAT AUTO has decided to raise its standards to world class level, as reflected in World Class Manufacturing (WCM) route map. Together with leading European and Japanese experts, we have defined our production system that embraces the entire organization of the factory, involving quality system, maintenance system, cost management and logistic with in evolutionary perspective.FIAT is a World Class Manufacturer where SAFETY and its Awareness is an essential value.

Example While keeping the pallet for PWT unloading it could dash to the operator, thus guards were provided to restrict the pallet position in order to safeguard the operator.

Example 1
In february,2013 there were 9 defects related to Alternator bracket bolt loose. To find its root cause we used the tool TWTP (The Way to Teach People). On using TWTP it was found that the root cause was process weakness.The root cause was eliminated by changing the torquing sequence of the Alternator Bracket and an OPL (One Point Lesson) showing the torquing sequence was displayed at O.P 70 were the above operation is carried out.
(Alternator Bracket bolt loose)
ONE POINT LESSON(OPL) SHEET Changed Torquing Sequence of Alternator Bracket.

N.V.A.A REDUCTION BY MERGING PDI-PRODUCTION WITH CARE AND PDI-QUALITY
PDI PRODUCTION and PDI QUALITY, which were earlier done offline are now being done online. After doing a thorough study of the inspection points of CARE, PDI PRODUCTION and PDI QUALITY it was found that PDI PRODUCTION had most of the inspection points common with CARE and PDI QUALITY, therefore a proposal to eliminate PDI PRODUCTION has been made.Eliminating PDI PRODUCTION will reduce Non-Value Added Activity (NVAA) and In saturation present in main line.

NEW PRODUCT INTRODUCTION (EURO-5 95 HP 1.3 SDE)
PROJECT 4
OBJECTIVE:-
Assembly of 1.3 SDE TATA 95HP EURO 5 in existing Production Line (Trimming Assembly Line) with Desired Quality, Safety and Minimum cost.
ACTIVITY PLAN:-• Comparison of Euro-4 and Euro-5 operations.• Prepare the list of tooling, jig, fixtures and equipment required.• Identify the modification of existing processes.• Implement the changes required in existing processes.• Identify the sources for procurement.• Conduct Trial Assembly of EURO-5 Engine on Existing line.• Prepare the list of exclusive operations.• Record the observations.• Reaction plan to deviations / Observations.• Correction of Process . • Trial run.• PPAP• Delivery
35
Comparison of EURO-4 & EURO -5 operations:-
On comparing the History Sheet of EURO-4 AND EURO-5 engine we observed the following additional parts need to assemble EURO 5 Engine :-
• Oil rubber cap• Post Card sensor connector bracket• Bracket for throttle body• Adaptor with O Ring• Lambda sensor clips• Gasket TC outlet to assembly pipe• Reverse indicator W/H connection• Temperature sensor
36
PROCESS MODIFICATION:-Process No-1 :- Assembling and Disassembling of A Mount bracket.
As per TML, first batch of imported 96 engines will come with FIAT Imported Engines Mounting bracket (A Mount) which needs to be replaced at FIAL also an additional bracket for Temp. sensor is to be assembled along with engine mounting bkt (A mount). We cannot perform this activity on Mainline due to its cycle time and non-availability of tool required. So this activity to be performed on Pilot Line itself.
Tools Required:- ENR with 60Nm Torque, Reaction arm to resist Torque.
Problem Description:-Disassembly and Assembly of ‘A’ mount bracket activity will result heavy thrust on the arm of operator.
Proposal:-1. Engine will transfer to Engine assembly to dismantle and assemble of ‘A’ mount bracket
and again transfer to Trim Plant.2. Facility to be provided in Trim–Pilot line for dismantle and assemble of ‘A’ mount
bracket .
Proposal Validation 1:-1. Engine will transfer to Engine assembly to dismantle and assemble of ‘A’ mount bracket and again transfer to Trim Plant.
37
Disadvantage :-• Transport arrangement to be made for engine transfer from Trim Plant to engine
assembly and Vice –Versa• Pallet to be made for storage of engine• Chances of damage of engine while multiple handling• Time consuming activity• Additional man power required for transport activity
Proposal Validation 2:-
2. Facility to be provided in Trim – Pilot line for dismantle and assemble of ‘A’ mount bracket
Available Source:-Nut runner of 60 Nm torque
Feasibility Study:-
1. Dismantling and assembling of ‘A’ mount bracket is possible in pilot line and transferred to main line for further assembly by minimum movement.
2. But no arrangement to resist the reaction force developed by nut runner while performing activity (60 Nm)
38
Idea:-Provision of reaction arm for 60 Nm torque nut runner
Cost of Development of Reaction Arm :-1. Out source2. In-house
Out source:-Development cost of Reaction arm is Rs 348242/-

In-House:-Reaction arm can be made in house with minimum cost than out source
Execution :-Materials for manufacturing the reaction arm are used from scrap
Solution :-
40
Benefit :-
•Scrap material cost – Rs 1000/-•Labor Cost (BC) :- 45/Hr•Salaried Emp Cost (WC) :- 435/Hr•Duration :- 8Hrs•45*8+435*8+1000 =Rs 4840/-
• Development cost of Reaction arm is Rs 348242/-
Outsource In-House
B/C
Project benefit :-
348242 - 4840 = Rs 3,43,402
343402 / 4840 = 71.95
41
Process No-2 :- Clutch kit assembly
Imported engines will come without clutch kit; Clutch kit assembly is carryover from existing Tata BS4 SDE90. This activity can’t be performed on Main Line due to cycle time and unavailability of tools required on the line as earlier this operation is performed in Engine Plant itself. So this activity also to be performed on Pilot Line.
Tools Required:-
• Clutch Plate Pressing Tool• Jig Fixture
Action Taken:-
Station was created by availing the tools required on Pilot Line. For clutch kit, first preference to be given to M/s. Luk & incase not available M/s. Valeo to be used.
