For this we calculate the masses to be used according to the parts of each engine and we report them on the crank pins of the connecting rods at the time of balancing using machined “bobweights”.

This method makes it possible to replace a defective flywheel without having to disassemble the crankshaft from the engine in many cases. We also balance the clutch independently for the same reason. However, this is only valid for the steel and heavy clutch mechanisms of older generation engines.

Connecting rods machined in H (example: Carrillo connecting rods) offer the best stiffness\/mass compromise and are therefore to be preferred when fitting a competition engine. Attention: the mass of the connecting rod must be taken into account when balancing a crankshaft in V<\/strong> (or odd number of cylinders). A change in the mass of the connecting rod necessarily requires a rebalancing of the crankshaft in the case of V engines.<\/p>\n <\/p>\n The pistons must be as light as possible<\/strong> (always within the limits of reliability) in order to reduce the forces on the cylinder walls as well as on the connecting rod and its bearing. The use of forged pistons<\/strong> (example: CP Carrillo pistons, Mahle pistons, Wossner pistons, etc.) is recommended when preparing an engine. The forging then machining process guarantees the greatest robustness for a limited mass, with controlled thermal expansion<\/strong> . Attention: the mass of the piston must be taken into account when balancing a crankshaft in V (or odd number of cylinders). A change in the mass of the piston necessarily requires a rebalancing of the crankshaft in the case of V engines<\/strong> .<\/p>\n <\/p>\n The lightening of the flywheel is a matter of compromise between engine acyclism and the dynamics of revving<\/strong> . A heavy flywheel will make it possible to filter the torque pulsations due to the combustion of each cylinder (important on a single cylinder for example) but will penalize acceleration at equal engine power. An engine with a high number of cylinders (example V10 or V12) will use a relatively light flywheel, the time between each combustion being shorter and the engine torque more “constant” over a cycle. In the case of multi-cylinder automobile competition engines, the flywheel must be as light as possible. Reducing acylism is then not a priority and it is important to favor the acceleration phases.<\/p>\n IMPORTANT: Contrary to popular belief, a heavy flywheel does not provide torque to the engine<\/strong> . It adds inertia at most and somewhat \u201clinearizes\u201d the return of power during acceleration phases (no influence in steady state), which can provide \u201ctraction\u201d in certain cases (off-road or on a motorcycle for example) but in no case of the engine torque\u2026. The torque feel is actually \u201csmooth\u201d rather than snappy on acceleration.<\/strong> The latter being less violent, this reduces slippage, hence the gain in grip or traction in some cases.<\/p>\n To conclude, the lighter the flywheel, the faster the car accelerates at equal power, especially in the first gear ratios (where the acceleration is greatest). The car accelerates faster but will keep the same top speed in all cases (light or heavy flywheel).<\/p>\n Lightening the flywheel is equivalent to lightening the car in terms of acceleration<\/strong> , we gain on the inertia of the car (in rotation), the mass of the vehicle being a translation inertia.<\/p>\n <\/p>\n The damper pulley adds a damped mass<\/strong> (precisely calculated by the manufacturer) in order to minimize the harmful effect of resonance frequencies on the crankshaft and flywheel assembly. Some engines are more sensitive than others to this phenomenon (6 cylinders in line for example) and it is therefore necessary to be extremely vigilant when modifying this part according to each application<\/strong> .<\/p>\n <\/p>\n The crankshaft<\/strong> is a moving part which must therefore be light, but it must also absorb a large number of mechanical stresses,<\/strong> hence the multiple counterweights which allow (in addition to their role of dynamic balancing) to limit the internal tensions, the bending of the crankshaft and thus the load at the level of the line bearings . A competition crankshaft will have a maximum of counterweights (8 counterweights on a 4-cylinder in-line) while a production crankshaft will be satisfied with fewer counterweights in order to facilitate its production and lower its cost (4 counterweights on a 4-cylinder in-line ). Consequently, the counterweights of a crankshaft depend on the mass of the moving parts attached to it (connecting rod, piston). They are present in order to balance and reduce the dynamic bending of the crankshaft during high revs. (Formula 1 engines use heavy metal inserts to increase crankshaft density in certain areas). It is therefore not necessary to lighten a crankshaft excessively at the risk of reducing its reliability<\/strong> . Ultimately the lightening of the crankshaft is to be considered on a case-by-case basis. It is often wiser to focus on lightening the peripheral parts (flywheel, connecting rods, pistons, etc.) rather than on the crankshaft itself. In the case of V-shaped engines, it is very difficult to lighten a crankshaft without carrying out a thorough dynamic study, otherwise balancing will be impossible afterwards.<\/p>\n The use of steel crankshafts specifically designed for racing (example: Arrow steel crankshafts) is recommended for high-efficiency engines.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”2_3″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_image src=”https:\/\/www.lorrtec.com\/wp-content\/uploads\/2020\/05\/controle-villebrequin-sur-banc-alignement-paliers-comparateur-1-1.jpg” alt=”Alignment check of the crankshaft bearings on a comparator bench” title_text=”check-crankshaft-on-bench-alignment-bearings-comparator-” show_in_lightbox=”on” align_tablet=”center” align_phone=”” align_last_edited=”on|desktop” admin_label=”r\u00e9alisation de faisceaux moteurs en fil d’argent” _builder_version=”4.4.6″][\/et_pb_image][et_pb_image src=”https:\/\/www.lorrtec.com\/wp-content\/uploads\/2020\/05\/equilibrage-avec-volant-moteur-poulie-damper-.jpg” alt=”Crankshaft balancing with flywheel and damper pulley” title_text=”balancing-with-flywheel-pulley-damper-” show_in_lightbox=”on” align_tablet=”center” align_phone=”” align_last_edited=”on|desktop” admin_label=”un bo\u00eetier \u00e9lectronique MOTEC PMD30 et un MOTEC M150″ _builder_version=”4.4.6″][\/et_pb_image][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=RJ-g3fg-uHQ” _builder_version=”4.4.6″ custom_margin=”||3px|||”][\/et_pb_video][et_pb_text _builder_version=”4.4.6″ text_font=”||on||||||” text_orientation=”center”]Chevrolet V8 crankshaft balancing with bobweights[\/et_pb_text][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=QuKdNQvq2Jo” _builder_version=”4.4.6″ custom_margin=”||3px|||”][\/et_pb_video][et_pb_text _builder_version=”4.4.6″ text_font=”||on||||||” text_orientation=”center”]Ford GT40 V8 Engine Tuning[\/et_pb_text][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=i0WDPiociXQ” _builder_version=”4.4.6″ custom_margin=”||3px|||”][\/et_pb_video][et_pb_text _builder_version=”4.4.6″ text_font=”||on||||||” text_orientation=”center”]PORSCHE crankshaft balancing – Atelier LORRTEC on Schenck Pasio[\/et_pb_text][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=XoPPc2-OyTg” _builder_version=”4.4.6″ custom_margin=”||3px|||”][\/et_pb_video][et_pb_text _builder_version=”4.4.6″ text_font=”||on||||||” text_orientation=”center”]Switching to the V10 VIPER GTS-R (GT2) engine test bench – LORRTEC engine test bench[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_3,1_3″ module_class=” et_pb_row_fullwidth” _builder_version=”3.25″ width=”89%” width_tablet=”80%” width_phone=”” width_last_edited=”on|desktop” max_width=”89%” max_width_tablet=”80%” max_width_phone=”” max_width_last_edited=”on|desktop” make_fullwidth=”on”][et_pb_column type=”2_3″ _builder_version=”3.25″ custom_padding=”|||” custom_padding__hover=”|||”][et_pb_text admin_label=”Comment connecter le bo\u00eetier \u00e0 des capteurs d’origines ?” _builder_version=”4.4.6″ text_text_color=”#ffffff” quote_text_align=”justify” header_text_color=”#ffffff” header_2_text_color=”#ffffff” header_3_text_color=”#ffffff” text_orientation=”justified”]<\/p>\n The crankshaft<\/strong> is a moving part which must therefore be light, but it must also absorb a large number of mechanical stresses,<\/strong> hence the multiple counterweights which allow (in addition to their role of dynamic balancing) to limit the internal tensions, the bending of the crankshaft and thus the load at the level of the line bearings .
